libceph: use timespec64 for r_mtime

Browse Source 
The request mtime field is used all over ceph, and is currently
represented as a 'timespec' structure in Linux. This changes it to
timespec64 to allow times beyond 2038, modifying all users at the
same time.

[ Remove now redundant ts variable in writepage_nounlock(). ]
