LU-15721 llite: only statfs for projid if PROJINHERIT set

If projid is set on a directory but PROJINHERIT is not, do not report
the project quota for statfs.  This matches how ext4_statfs() and
xfs_fs_statfs() behave, on which Lustre project quota is modelled.

Fixes: e5c8f6670f ("LU-9555 quota: df should return projid-specific values")
