quota: fix wrong condition in is_quota_modification()
commit 6565c182094f69e4ffdece337d395eb7ec760efc upstream.
Quoted from
commit 3da40c7b0898 ("ext4: only call ext4_truncate when size <= isize")
" At LSF we decided that if we truncate up from isize we shouldn't trim
fallocated blocks that were fallocated with KEEP_SIZE and are past the
new i_size. This patch fixes ext4 to do this. "
And generic/092 of fstest have covered this case for long time, however
is_quota_modification() didn't adjust based on that rule, so that in
below condition, we will lose to quota block change:
- fallocate blocks beyond EOF
- remount
- truncate(file_path, file_size)
Fix it.
