RDMA/mlx4: Ensure that maximal send/receive SGE less than supported by HW
In calculating the global maximum number of the Scatter/Gather elements
supported, the following four maximum parameters must be taken into
consideration: max_sg_rq, max_sg_sq, max_desc_sz_rq and max_desc_sz_sq.
However instead of bringing this complexity to query_device, which still
won't be sufficient anyway (the calculations are dependent on QP type),
the safer approach will be to restore old code, which will give us 32
SGEs.
Fixes: 33023fb85a42 ("IB/core: add max_send_sge and max_recv_sge attributes")
