Kaike Wan 93b289b9af IB/hfi1: Clear the IOWAIT pending bits when QP is put into error state 
When a QP is put into error state, it may be waiting for send engine
resources. In this case, the QP will be removed from the send engine's
waiting list, but its IOWAIT pending bits are not cleared. This will
normally not have any major impact as the QP is being destroyed.  However,
the QP still needs to wind down its operations, such as draining the send
queue by scheduling the send engine. Clearing the pending bits will avoid
any potential complications. In addition, if the QP will eventually hang,
clearing the pending bits can help debugging by presenting a consistent
picture if the user dumps the qp_stats.

This patch clears a QP's IOWAIT_PENDING_IB and IO_PENDING_TID bits in
priv->s_iowait.flags in this case.
