ceph: stop using current_kernel_time()
ceph_mdsc_create_request() is one of the last callers of the deprecated current_kernel_time() as well as timespec_trunc(). This changes it to use the timespec64 based interfaces instead, though we still need to convert the result until we are ready to change over req->r_stamp. The output of the two functions, ktime_get_coarse_real_ts64() and current_kernel_time() is the same coarse-granular timestamp, the only difference here is that ktime_get_coarse_real_ts64() doesn't overflow in 2038.
