scsi: lpfc: use monotonic timestamps for statistics
The get_seconds() function suffers from a possible overflow in 2038 or 2106, as well as jitter due to settimeofday or leap second updates, and is deprecated. As we are interested in elapsed time only, using ktime_get_seconds() to read the CLOCK_MONOTONIC timebase is ideal here. This also lets us remove the hack that tries to deal with get_seconds() going slightly backwards, which cannot happen with montonic timestamps.
