[PATCH v6 4/8] scsi: ibmvfc: extend async event handlers to handle async sub queue events

Refactor async event handling to support both traditional async CRQs and
new asynchronous sub-queue CRQs.

Modify ibmvfc_handle_async() to accept events from either source and
update ibmvfc_process_async_work() to handle both ibmvfc_async_crq and
ibmvfc_async_subq structures. Add is_subq flag to ibmvfc_async_work to
distinguish between event sources.

Add ibmvfc_full_fpin_to_desc() to convert full FPIN messages from async
sub-queue format to fc_els_fpin structures. Update FPIN processing logic
to extract WWPN, node_name, and scsi_id from the appropriate structure
based on event source.

Update KUnit tests to reflect the new async event handling interface.
