md: Fix failed allocation of md_register_thread
commit e406f12dde1a8375d77ea02d91f313fb1a9c6aec upstream.
mddev->sync_thread can be set to NULL on kzalloc failure downstream.
The patch checks for such a scenario and frees allocated resources.
Committer node:
Added similar fix to raid5.c, as suggested by Guoqing.
