Stephen Brennan 512286ddc3 ext4: use ext4_grp_locked_error in mb_find_extent ...

commit cd84bbbac1 upstream.

Commit 5d1b1b3f49 ("ext4: fix BUG when calling ext4_error with locked
block group") introduces ext4_grp_locked_error to handle unlocking a
group in error cases. Otherwise, there is a possibility of a sleep while
atomic. However, since 43c73221b3 ("ext4: replace BUG_ON with WARN_ON
in mb_find_extent()"), mb_find_extent() has contained a ext4_error()
call while a group spinlock is held. Replace this with
ext4_grp_locked_error.

Fixes: 43c73221b3 ("ext4: replace BUG_ON with WARN_ON in mb_find_extent()")
