Dean Luick 1afac08b39 IB/hfi1: Correctly move list in sc_disable() 
Commit 13bac86195 ("IB/hfi1: Fix abba locking issue with sc_disable()")
incorrectly tries to move a list from one list head to another.  The
result is a kernel crash.

The crash is triggered when a link goes down and there are waiters for a
send to complete.  The following signature is seen:

  BUG: kernel NULL pointer dereference, address: 0000000000000030
  [...]
  Call Trace:
   sc_disable+0x1ba/0x240 [hfi1]
   pio_freeze+0x3d/0x60 [hfi1]
   handle_freeze+0x27/0x1b0 [hfi1]
   process_one_work+0x1b0/0x380
   ? process_one_work+0x380/0x380
   worker_thread+0x30/0x360
   ? process_one_work+0x380/0x380
   kthread+0xd7/0x100
   ? kthread_complete_and_exit+0x20/0x20
   ret_from_fork+0x1f/0x30

The fix is to use the correct call to move the list.
