ext4: convert BUG_ON's to WARN_ON's in mballoc.c
[ Upstream commit
907ea529fc4c3296701d2bfc8b831dd2a8121a34 ]
If the in-core buddy bitmap gets corrupted (or out of sync with the
block bitmap), issue a WARN_ON and try to recover. In most cases this
involves skipping trying to allocate out of a particular block group.
We can end up declaring the file system corrupted, which is fair,
since the file system probably should be checked before we proceed any
further.
