scsi: smartpqi: remove set but not used variable 'ctrl_info'

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

drivers/scsi/smartpqi/smartpqi_init.c: In function 'pqi_driver_version_show':
drivers/scsi/smartpqi/smartpqi_init.c:6164:24: warning:
 variable 'ctrl_info' set but not used [-Wunused-but-set-variable]

commit 6d90615f13 ("scsi: smartpqi: add sysfs entries") added it but
it was never used. Also remove variable 'shost'.
