Subject: [PATCH] mpt2sas: fix -Wunused-variable warning

Fix for:
drivers/scsi/mpt2sas/mpt2sas_scsih.c: In function
  ‘_scsih_sas_broadcast_primative_event’:
drivers/scsi/mpt2sas/mpt2sas_scsih.c:5766:40: warning: unused
  variable ‘event_data’ [-Wunused-variable]

remove Mpi2EventDataSasBroadcastPrimitive_t *event_data,
use fw_event->event_data directly instead.
