[PATCH v2] xfs_quota: fix false error reporting of project inheritance flag is not set

[Achilles Gaikwad <agaikwad@redhat.com>]

After kernel commit:

9336e3a7 "xfs: project id inheritance is a directory only flag"

xfs stopped setting the project inheritance flag on regular files, but
userspace quota code still checks for it and will now issue the error:

"project inheritance flag is not set"

for every regular file during quotacheck.  Fix this by only checking
for the flag on directories.
