drm/tests: shmem: Hold reservation lock around purge
Acquire and release the GEM object's reservation lock around calls
to the object's purge operation. The tests use
drm_gem_shmem_purge_locked(), which led to errors such as show below.
[ 58.709128] WARNING: CPU: 1 PID: 1354 at drivers/gpu/drm/drm_gem_shmem_helper.c:515 drm_gem_shmem_purge_locked+0x51c/0x740
Only export the new helper drm_gem_shmem_purge() for Kunit tests.
This is not an interface for regular drivers.
