reiserfs: use monotonic time for j_trans_start_time
Using CLOCK_REALTIME time_t timestamps breaks on 32-bit systems in 2038, and gives surprising results with a concurrent settimeofday(). This changes the reiserfs journal timestamps to use ktime_get_seconds() instead, which makes it use a 64-bit CLOCK_MONOTONIC stamp. In the procfs output, the monotonic timestamp needs to be converted back to CLOCK_REALTIME to keep the existing ABI.
