[IPV6]: Fix the return value of ipv6_getsockopt
If CONFIG_NETFILTER if not selected when compile the kernel source code, ipv6_getsockopt will returen an EINVAL error if optname is not supported by the kernel. But if CONFIG_NETFILTER is selected, ENOPROTOOPT error will be return. This patch fix to always return ENOPROTOOPT error if optname argument of ipv6_getsockopt is not supported by the kernel.
