  SVN rev 186565 on 2008-12-29 13:25:58Z by kib
  
  When the insmntque() in the pfs_vncache_alloc() fails, vop_reclaim calls
  pfs_vncache_free() that removes pvd from the list, while it is not yet
  put on the list.
  
  Prevent the invalid removal from the list by clearing pvd_next and
  pvd_prev for the newly allocated pvd, and only move pfs_vncache list
  head when the pvd was at the head.
