ceph: use ktime_to_timespec64() rather than jiffies_to_timespec64()
Latencies are of type ktime_t, coverting from jiffies is incorrect. Also, switch to "struct ceph_timespec" for r/w/m latencies. Signed-off-by: Venky Shankar <vshankar@redhat.com> Reviewed-by: Xiubo Li <xiubli@redhat.com> Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
