ceph: update issue_seq on cap grant 



We need to update the issue_seq on any grant operation, be it via an MDS
reply or a separate grant message.  The update in the grant path was
missing.  This broke cap release for inodes in which the MDS sent an
explicit grant message that was not soon after followed by a successful
MDS reply on the same inode.

Also fix the signedness on seq locals.
