Pull request overview
This PR improves error handling and initialization order in the module adapter creation flow for data processing tasks. The changes ensure that task creation failures are properly detected and handled, prevent potential use-after-free issues, and guarantee that module fields are initialized before the DP thread can access them.
Changes:
- Add error checking for DP task initialization to catch creation failures
- Fix task pointer assignment to only occur on successful initialization
- Reorder module field initialization to happen before DP thread creation

Move mod field initialization in module_adapter_new_ext() before creating the dp thread. Moving the initialization earlier prevents the dp thread from use uninitialized data. Signed-off-by: Adrian Warecki <adrian.warecki@intel.com>
Check the value returned by the pipeline_comp_dp_task_init() call in module_adapter_new_ext(). Update scheduler_dp_task_init() to assign the output task structure pointer only on success. The function allocates task structure and free it on failure. Returning a non-null task on error could lead to a double free in the module adapter or use after free.

Fix use after free in module_adapter_new_ext() by removing the dst access after freeing mod. The dst points to a field inside the previously allocated mod structure. The structure is freed on error so its fields do not need to be cleared beforehand. Signed-off-by: Adrian Warecki <adrian.warecki@intel.com>

Remove the no longer needed user_memory_init_shared(). Add the dp thread to the memory domain directly in the dp scheduler. The function originally added the common partition to the memory domain and added thread to that domain. The userspace proxy now adds the common partition to memory domain, so the function cannot perform this step. Grant access to thread only when userspace is used. Kernel threads have access to all the memory, no need to additionally grant access to them. Signed-off-by: Adrian Warecki <adrian.warecki@intel.com>

pipeline_comp_dp_task_init()to ensure the dp thread is created successfully. This prevents execution from continuing with an invalid task.scheduler_dp_task_init()to assign the output task pointer only on success. The function frees the allocated task structure on failure, so returning a non-null task could lead to a double free or use after free.module_adapter_new_ext()to occur before creating the dp thread. This prevents the thread from use uninitialized fields.
