scsi: megaraid: Remove redundant assignment to variable mfiStatus

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 its 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]
