scsi: fnic: Use time64_t to represent trace timestamps 

Trace timestamps use struct timespec and CURRENT_TIME which are not
y2038 safe.  These timestamps are only part of the trace log on the
machine and are not shared with the fnic.  Replace then with y2038 safe
struct timespec64 and ktime_get_real_ts64(), respectively.
