include/ceph_fs: correct ceph_mds_cap_item field name

Originally, the last_sent sequence from the MDS was sent by the client during
bulk cap release but it was shortly after changed to the last_issue which is
the sequence number that the cap was originally "issued" by the MDS rank (which
may be updated after import of caps).
