After 7d79b40b ("e2fsck: adjust quota counters when clearing orphaned
inodes"), we load all the quotas before we process the orphaned inodes,
and when we load the quotas, we check the checsum of the bbitmap for each
group. If one of the bbitmap checksums is wrong, the following error will
be reported:
“Error initializing quota context in support library:
Block bitmap checksum does not match bitmap”
But loading quotas comes before checking the current superblock for the
EXT2_ERROR_FS flag, which makes it impossible to use e2fsck to repair any
image that contains orphan inodes and has the wrong bbitmap checksum.
So delaying quota loading until after the EXT2_ERROR_FS judgment avoids
the above problem.
