ip6mr: Remove MFC_NOTIFY and refactor flags

MFC_NOTIFY exists in ip6mr, probably as some legacy code [was already removed for ipmr in commit 06bd6c0 ("net: ipmr: remove unused MFC_NOTIFY flag and make the flags enum"). Remove it from ip6mr as well, and move the enum into a common file; Notice MFC_OFFLOAD is currently only used by ipmr.
