scsi: lpfc: Alter FPIN stat accounting logic

When configuring CMF management based on signals instead of FPINs, FPIN
alarm and warning statistics are not tracked.

Change the behavior so that FPIN alarms and warnings are always tracked
regardless of the configured mode.

Similar changes are made in the CMF signal stat accounting logic.  Upon
receipt of a signal, only track signaled alarms and warnings. FPIN stats
should not be incremented upon receipt of a signal.
