ceph: fix uid/gid on resent mds requests
MDS requests can be rebuilt and resent in non-process context, but were
filling in uid/gid from current_fsuid/gid. Put that information in the
request struct on request setup.
This fixes incorrect (and root) uid/gid getting set for requests that
are forwarded between MDSs, usually due to metadata migrations.
