Baokun Li 78327acd4c ext4: regenerate buddy after block freeing failed if under fc replay 
[ Upstream commit c9b528c35795b711331ed36dc3dbee90d5812d4e ]

This mostly reverts commit 6bd97bf273 ("ext4: remove redundant
mb_regenerate_buddy()") and reintroduces mb_regenerate_buddy(). Based on
code in mb_free_blocks(), fast commit replay can end up marking as free
blocks that are already marked as such. This causes corruption of the
buddy bitmap so we need to regenerate it in that case.
