ice: Fix the calculation of ICE_MAX_MTU
Currently ICE_MAX_MTU subtracts only ETH_HLEN from max frame size and
adds ETH_FCS_LEN and VLAN_HLEN, which is not what was intended.
The ETH_HLEN + ETH_FCS_LEN + VLAN_HLEN expression should be surrounded
with parentheses.
Wrap mentioned expression and take into account VLAN double tagging.
