IB/mlx4: Return receive queue sizes for userspace QPs from query QP
Return the receive queue sizes for both userspace QPs and kernel Qps
(not just kernel QPs) from mlx4_ib_query_qp(). Also zero the send
queue sizes for userspace QPs to avoid a possible information leak,
and set the max_inline_data for kernel QPs to 0 since inline sends are
not supported for kernel QPs.
