6 serious fixes:
1) Hold the mutex around the find and corresponding update of our gid
2) The ifa list is rcu protected, copy its contents under rcu to avoid
using a freed structure
3) On error, netdev might be null, so check it before trying to release it
4) On init, if workqueue alloc fails, fail init
5) The new demux patches exposed a bug in mlx5 and ipath drivers, we need
to use the payload P_Key to determine the P_Key the packet arrived on
because the hardware doesn't tell us the truth
6) Due to a couple convoluted error flows, it is possible for the CM to
trigger a use_after_free and a double_free of rb nodes. Add two
checks to prevent that. This code has worked for 10+ years. It is
likely that some of the recent changes have caused this issue to
surface. The current patch will protect us from nasty events for
now while we track down why this is just now showing up.
