[PATCH for-rc v3 4/8] RDMA/bnxt_re: Initialize wqe.flags in bnxt_re_post_srq_recv()

[Selvin Xavier <selvin.xavier@broadcom.com>]

wqe is declared once above the WR loop and never zeroed, so
wqe.flags holds indeterminate stack contents on the first WR and the
previous WR's stale value thereafter. This propagates straight into
the hardware-visible srqe->flags in bnxt_qplib_post_srq_recv().

Most values of the wqe struct is set except flags. So initialize
flags also.

Fixes: 37cb11acf1f7 ("RDMA/bnxt_re: Add SRQ support for Broadcom adapters")
