IB/rxe: Clear queue buffer when modifying QP to reset

Browse Source 
RXE resets the send-q only once in rxe_qp_init_req() when
QP is created, but when the QP is reused after QP reset, the send-q
holds previous garbage data.

This garbage data wrongly fails CQEs that otherwise
should have completed successfully.
