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.
