  Log:
  Fix a bug introduced in 1.11 (and also MFCd to stable AND the security branch)
  that causes a machine to panic when the kernel PPP / DEFLATE code is used.
  1.11 moved a ZFREE to a point after the structural members were clobbered
  by stores into a union'd structure.
  
  This commit fixes the bug and adds a big whopping comment to make sure
  the code isn't 'cleaned up' again :-)
  
  Ian Dowse came up with the same patch independantly 68 seconds before I
  did, talk about Karma!
  
  I would also like to thank Eugene Grosbein for marathon work in tracking the
  problem down by udpating his -stable based on date over and over again
  to close in on the commit that caused his crashes.
