net: liquidio: Remove set but not used variable

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

drivers/net/ethernet/cavium/liquidio/octeon_device.c: In function lio_pci_readq:
drivers/net/ethernet/cavium/liquidio/octeon_device.c:1327:6: warning: variable ‘val32’ set but not used [-Wunused-but-set-variable]

drivers/net/ethernet/cavium/liquidio/octeon_device.c: In function lio_pci_writeq:
drivers/net/ethernet/cavium/liquidio/octeon_device.c:1358:6: warning: variable ‘val32’ set but not used [-Wunused-but-set-variable]

these variable is never used, so remove it.
