vrf: Do not attempt to create IPv6 mcast rule if IPv6 is disabled
A user reported that vrf create fails when IPv6 is disabled at boot using
'ipv6.disable=1':
https://bugzilla.kernel.org/show_bug.cgi?id=204903
The failure is adding fib rules at create time. Add RTNL_FAMILY_IP6MR to
the check in vrf_fib_rule if ipv6_mod_enabled is disabled.
Fixes: e4a38c0c4b27 ("ipv6: add vrf table handling code for ipv6 mcast")
