This patch corrects a problem in the TruCluster DLM subsystem in which
a node can panic with the panic string "convert_lock: bad lock state"
and the stack trace as follows:

   0 stop_secondary_cpu()
   1 panic()
   2 event_timeout(func = 0xfffffc000028ee80, arg = 0xfffffc00008ad630)
   3 xcpu_puts()
   4 printf()
   5 panic()
   6 convert_lock()
   7 dlm_convert()
   8 syscall()
   9 _Xsyscall()
