Merge in.c:1.89,1.90 from HEAD to RELENG_6_0:

  Acquire Giant conditionally in in_addmulti() and in_delmulti() based on
  whether the interface being accessed is IFF_NEEDSGIANT or not.  This
  avoids lock order reversals when calling into the interface ioctl
  handler, which could potentially lead to deadlock.

  The long term solution is to eliminate non-MPSAFE network drivers.

  Discussed with: jhb

  Unlock Giant symmetrically with respect to lock acquire order as that's
  generally nicer.
