xfrm: check user specified spi for IPComp
IPComp connection between two hosts is broken if given spi bigger
than 0xffff.
OUTSPI=0x87
INSPI=0x11112

tcpdump can capture outbound ping packet, but inbound packet is
dropped with XfrmOutNoStates errors. It looks like spi value used
for IPComp is expected to be 16bits wide only.
