scsi: qla2xxx: Inline the qla2x00_fcport_event_handler() function



Instead of calling qla2x00_fcport_event_handler() and letting the switch
statement inside that function decide which other function to call, call
the latter function directly. Remove the event member from the event_arg
structure because it is no longer needed. Remove the
qla_handle_els_plogi_done() function because it is never called.
