ip6mr: only set ip6mr_table from setsockopt when ip6mr_new_table succeeds
commit 848235edb5c93ed086700584c8ff64f6d7fc778d upstream.
Currently, raw6_sk(sk)->ip6mr_table is set unconditionally during
ip6_mroute_setsockopt(MRT6_TABLE). A subsequent attempt at the same
setsockopt will fail with -ENOENT, since we haven't actually created
that table.
A similar fix for ipv4 was included in commit 5e1859fbcc3c ("ipv4: ipmr:
various fixes and cleanups").
Fixes: d1db275dd3f6 ("ipv6: ip6mr: support multiple tables")
