scsi: fusion: Remove unused variable 'rc'

[ Upstream commit bd65694223f7ad11c790ab63ad1af87a771192ee ]

The return value of scsi_device_reprobe() is currently ignored in
_scsih_reprobe_lun(). Fixing the calling code to deal with the potential
error is non-trivial, so for now just WARN_ON().

The handling of scsi_device_reprobe()'s return value refers to
_scsih_reprobe_lun() and the following link:
