vfs: Add BUG_ON for delayed and unwritten flags in submit_bh()
The BH_Delay and BH_Unwritten flags should never leak out to
submit_bh(). So add some BUG_ON() checks to submit_bh so we can get a
stack trace and determine how and why this might have happened.
(Note that only XFS and ext4 use these buffer head flags, and XFS does
not use submit_bh(). So this patch should only modify behavior for
ext4.)
