Subject: [PATCH net-next] net: marvell: Remove set but not used variable

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

drivers/net/ethernet/marvell/pxa168_eth.c: In function pxa168_eth_change_mtu:
drivers/net/ethernet/marvell/pxa168_eth.c:1190:6: warning: variable ‘retval’ set but not used [-Wunused-but-set-variable]

`retval` is never used, so remove it.
