scsi: mpt3sas: Fix error return value in _scsih_expander_add()
When an expander does not contain any 'phys', an appropriate error code -1
should be returned, as done elsewhere in this function. However, we
currently do not explicitly assign this error code to 'rc'. As a result, 0
was incorrectly returned.
