netfilter: xt_ipcomp: Use ntohs to ease sparse warning

0-DAY kernel build testing backend reported: sparse warnings: (new ones prefixed by >>) >> >> net/netfilter/xt_ipcomp.c:63:26: sparse: restricted __be16 degrades to integer >> >> net/netfilter/xt_ipcomp.c:63:26: sparse: cast to restricted __be32 Fix this by using ntohs without shifting. Tested with: make C=1 CF=-D__CHECK_ENDIAN__
