The variable mfiStatus is assigned a value but it is never read. The
assignment is redundant and can be removed. Also remove { } as the
return statement does not need to be in it's own code block.

Cleans up clang scan build warning:
drivers/scsi/megaraid/megaraid_sas_base.c:4026:7: warning: Although the
value stored to 'mfiStatus' is used in the enclosing expression, the
value is never actually read from 'mfiStatus' [deadcode.DeadStores]
