ext4: don't over-report free space or inodes in statvfs

This fixes an analogus bug that was fixed in xfs in commit
4b8d867ca6 ("xfs: don't over-report free space or inodes in
statvfs") where statfs can report misleading / incorrect information
where project quota is enabled, and the free space is less than the
remaining quota.

This commit will resolve a test failure in generic/762 which tests for
this bug.
