tune2fs/fuse2fs/debugfs: after replaying the journal, fix up s_lastcheck
If the file system needs to have the journal replayed, but definition
it can't be freshly checked. So if the time when the file system was
last checked (s_lastcheck) is before the time it was last mounted
(s_mtime), force s_lastcheck to be before s_mtime.
This is necessary to make sure some of tune2fs's safety checks work
correctly after replaying the journal, since some of tune2fs's
operations really require that the file system be self-consistent or
grave damage can result.
