Mark Johnston 5a1e222bfd Close some races in multicast socket option handling. ... r333175 converted the global multicast lock to a sleepable sx lock, so the lock order with respect to the (non-sleepable) inp lock changed. To handle this, r333175 and r333505 added code to drop the inp lock, but this opened races that could leave multicast group description structures in an inconsistent state. This change fixes the problem by simply acquiring the global lock sooner. Along the way, this fixes some LORs and bogus error handling introduced in r333175, and commits some related cleanup.
