From: Andreas Dilger <[email protected]>

Add debugging for LASSERTF(it_disposition(it, DISP_ENQ_OPEN_REF)
in ll_file_open(), since this is a rarely hit failure under racer,
and it would be useful to get more information if this is hit
again.  Print the full intent disposition, as well as the status,
in case Oleg's earlier comment about bailing out on any error is
actually the case here.
