Aditya Pakki f61b68e1c7 md: Fix failed allocation of md_register_thread ...

commit e406f12dde 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.
