  Log:
  SVN rev 189229 on 2009-03-01 11:20:35Z by trasz
  
  MFC r188240:
  
  When a device containing mounted UFS filesystem disappears, the type
  of devvp becomes VBAD, which UFS incorrectly interprets as snapshot
  vnode, which in turns causes panic.  Fix it by replacing '!= VCHR'
  with '== VREG'.
  
  With this fix in place, you should no longer be able to panic the system
  by removing a device with an UFS filesystem mounted from it - assuming
  you don't use softupdates.
