[ Upstream commit f86b31c6a28f06eed3f6d9dc958079853b0792f1 ]

At first, driver allocates memory for NQ based on qplib_ctx->cq_count and
qplib_ctx->srqc_count.  Later when creating ring, it uses a static value
of 128K -1.

Fixing this with a static value for now.

Fixes: b08fe048a69d ("RDMA/bnxt_re: Refactor net ring allocation function")
