Mitko Haralanov 9636258f10 IB/hfi1: Remove dependence on qp->s_hdrwords ... The s_hdrwords variable was used to indicate whether a packet was already built on a previous iteration of the send engine. This variable assumed the protection of the QP's RVT_S_BUSY flag, which was required since the the QP's s_lock was dropped just prior to the packet being queued on the one of the egress mechanisms. Support for multiple send engine instantiations require that the field not be used due to concurency issues. The ps.txreq signals the "already built" without the potential concurency issues. Fix by getting rid of all s_hdrword usage. A wrapper is added to test for the already built case that used to use s_hdrwords. What used to be stored in s_hdrwords is now in the txreq. The PBC is not counted, but is added in the pio/sdma code paths prior to posting the packet.
