ceph: allow rename operation under different quota realms
Returning -EXDEV when trying to 'mv' files/directories from different
quota realms results in copy+unlink operations instead of the faster
CEPH_MDS_OP_RENAME. This will occur even when there aren't any quotas
set in the destination directory, or if there's enough space left for
the new file(s).
This patch adds a new helper function to be called on rename operations
which will allow these operations if they can be executed. This patch
mimics userland fuse client commit b8954e5734b3 ("client:
optimize rename operation under different quota root").
Since ceph_quota_is_same_realm() is now called only from this new
helper, make it static.
