scsi: lpfc: Enhance congestion statistics collection
Various improvements are made for collecting congestion statistics:
- Pre-existing logic is replaced with use of an hrtimer for increased
reporting accuracy.
- Congestion timestamp information is reorganized into a single struct.
- Common statistic collection logic is refactored into a helper routine.
