[RTEMS] Use spin lock for pool management
libgomp/
* libgomp/config/rtems/pool.h (gomp_thread_pool_reservoir): Use
pthread_spinlock_t instead of gomp_mutex_t lock.
(gomp_get_thread_pool): Likewise.
(gomp_release_thread_pool): Likewise.
* libgomp/config/rtems/proc.c (allocate_thread_pool_reservoir):
Likewise.
