[PATCH -next] scsi: pmcraid: remove set but not used variables 'res, access'

[YueHaibing]

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

drivers/scsi/pmcraid.c: In function 'pmcraid_abort_cmd':
drivers/scsi/pmcraid.c:2878:33: warning:
 variable 'res' set but not used [-Wunused-but-set-variable]

drivers/scsi/pmcraid.c: In function 'pmcraid_ioctl_passthrough':
drivers/scsi/pmcraid.c:3603:5: warning:
 variable 'access' set but not used [-Wunused-but-set-variable]

'res' never used since introduction in commit 89a368104150 ("[SCSI] pmcraid:
PMC-Sierra MaxRAID driver to support 6Gb/s SAS RAID controller")

'access' not used any more since commit
edb88cef0570 ("scsi: pmcraid: use normal copy_from_user")
