liquidio: remove set but not used variable 's'

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

drivers/net/ethernet/cavium/liquidio/lio_main.c: In function 'octeon_chip_specific_setup':
drivers/net/ethernet/cavium/liquidio/lio_main.c:1378:8: warning:
 variable 's' set but not used [-Wunused-but-set-variable]

It's not used since commit b6334be64d6f ("net/liquidio: Delete driver version assignment")
