Fix return value bug in px4_task_spawn_internal returning the arg-parsing
loop variable instead of the task index. Add pthread_attr_destroy calls
to prevent resource leaks on task creation failure, deletion, and exit.
Fix race condition in px4_task_delete by unlocking the mutex before
pthread_join and properly joining after pthread_cancel. Fix mutex unlock
placement in px4_task_exit to only unlock when the mutex was acquired.
