    xvcb lock order violation
    
    afs_FlushVCBs(1) = xvcb, xserver (in that order)
    
    afs_GetServer = xserver, xsrvAddr, (call afs_RemoveSrvAddr which calls
    afs_FlushServer, which gets xvcb)
    
    "nope". do a little dance to get xvcb, searching for a struct server to reuse
    again if we had to block.
    
    if you're curious:
    Lock afs_xserver status: (reader_waitingwriter_waiting, write_locked(pid:1589 at:36), 3 waiters)
    Lock afs_xvcb status: (none_waiting, write_locked(pid:0 at:273))
    Lock afs_xsrvAddr status: (none_waiting, write_locked(pid:1589 at:116))
