scsi: 53c700: Remove set but not used variable

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/scsi/53c700.c: In function NCR_700_intr:
drivers/scsi/53c700.c:1488:27: warning: variable ‘state’ set but not used [-Wunused-but-set-variable]

drivers/scsi/53c700.c: In function NCR_700_queuecommand_lck:
drivers/scsi/53c700.c:1742:26: warning: variable ‘direction’ set but not used [-Wunused-but-set-variable]

these variable is never used, so remove it.
