Sebastian Sanchez 626c077c02 IB/hfi1: Prevent link down request double queuing 
When link interrupts occur, multiple link down requests
could be queued up when only one is needed. This could get
the hfi1 out of sync with its link partner during LNI.

Only allow one link down request to be queued at any one time.
