qxl: send interrupt after migration in case ram->int_pending != 0, RHBZ #732949
if qxl_send_events was called from spice server context, and then migration had completed before a call to pipe_read, the target guest qxl driver didn't get the interrupt. In addition, qxl_send_events ignored further interrupts of the same kind, since ram->int_pending was set. As a result, the guest driver was stacked or very slow (when the waiting for the interrupt was with timeout).
