net/ice/base: fix for RSS hash on inner UDP port

Before this patch, only outer IP with inner UDP port can appear in
RSS hash, because the extraction sequence uses outer IP protocol
ID with Inner UDP protocol ID. ICE_PROT_UDP_OF always extracts the
TUNNELED UDP port values (i.e., 4789 for VXLAN). ICE_PROT_UDP_IL_OR_S
will extract NON-TUNNELED UDP port or inner UDP port.
