When rhashtable_init() fails, it returns -EINVAL.
However, since error return value of rhashtable_init is not checked,
it can cause use of uninitialized pointers.
So, fix unhandled errors of rhashtable_init.
The three patches are essentially the same logic.

v1->v2:
 - change commit message
 - fix possible memory leaks
v2->v3:
 - split patch into mlx5e, ipv6, mac80211
v3->v4:
 - fix newly created warnings due to patches in net/ipv6/seg6.c

  net/mlx5e: check return value of rhashtable_init
  net: ipv6: check return value of rhashtable_init
  net: mac80211: check return value of rhashtable_init
