scsi: lpfc: Introduce new attention types for lpfc_sli4_async_fc_evt() handler

Define new FC Link ACQE with new attention types 0x8 (Link Activation
Failure) and 0x9 (Link Reset Protocol Event).

Both attention types are meant to be informational-only type ACQEs with no
action required.

0x8 is reported for diagnostic purposes, while 0x9 is posted during a
normal link up transition when activating BB Credit Recovery feature.

As such, modify lpfc_sli4_async_fc_evt() logic to log the attention types
according to its severity and early return when informational-only
attention types are encountered.
