scsi: 3w-xxxx: Remove 2 unused variables 'response_que_value' and 'tw_dev' 

Fixes the following W=1 kernel build warning(s):

 drivers/scsi/3w-xxxx.c: In function ‘tw_empty_response_que’:
 drivers/scsi/3w-xxxx.c:463:24: warning: variable ‘response_que_value’ set but not used [-Wunused-but-set-variable]
 drivers/scsi/3w-xxxx.c: In function ‘tw_scsi_biosparam’:
 drivers/scsi/3w-xxxx.c:1345:23: warning: variable ‘tw_dev’ set but not used [-Wunused-but-set-variable]
