f2fs: don't over-report free space or inodes in statvfs
[ Upstream commit a9201960623287927bf5776de3f70fb2fbde7e02 ]
This fixes an analogus bug that was fixed in modern filesystems:
a) xfs in commit 4b8d867ca6e2 ("xfs: don't over-report free space or
inodes in statvfs")
b) ext4 in commit f87d3af74193 ("ext4: 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.
