Subject: [PATCH 4.4 22/28] RDMA/cxgb4: Fix the reported max_recv_sge value

From: Kamal Heib <kamalheib1@...il.com>

[ Upstream commit a372173bf314d374da4dd1155549d8ca7fc44709 ]

The max_recv_sge value is wrongly reported when calling query_qp, This is
happening due to a typo when assigning the max_recv_sge value, the value
of sq_max_sges was assigned instead of rq_max_sges.

Fixes: 3e5c02c9ef9a ("iw_cxgb4: Support query_qp() verb")
