ext4: add a hint for block bitmap corrupt state in mb_groups
[ Upstream commit 68ee261fb15457ecb17e3683cb4e6a4792ca5b71 ]
If one group is marked as block bitmap corrupted, its free blocks cannot
be used and its free count is also deducted from the global
sbi->s_freeclusters_counter. User might be confused about the absent
free space because we can't query the information about corrupted block
groups except unreliable error messages in syslog. So add a hint to show
block bitmap corrupted groups in mb_groups.
