Subject[PATCH] [SCSI] mpt2sas: fix build warning
Fixes this warning:

drivers/scsi/mpt2sas/mpt2sas_scsih.c: In function ‘_scsih_sas_broadcast_primitive_event’:
drivers/scsi/mpt2sas/mpt2sas_scsih.c:5810:40: warning: unused variable ‘event_data’ [-Wunused-variable]

when CONFIG_SCSI_MPT2SAS_LOGGING is not enabled.

Equivalent patches for drivers/message/fusion/mptdebug.h and
drivers/scsi/mpt3sas/mpt3sas_debug.h would fix similar, but to me
theoretical, warnings.
