[PATCH] scsi: mpt3sas: Fix missing unwind goto in mpt3sas_config_update_driver_trigger_pg3()

[Zhong Yong]

Smatch warns:
drivers/scsi/mpt3sas/mpt3sas_config.c:2478
mpt3sas_config_update_driver_trigger_pg3() warn: missing unwind goto?

Fix this by assigning '-EFAULT' to 'rc' and
changing the direct return to a goto 'out'.
