Subject: RDMA/bnxt_re: Static NQ depth allocation
Patch-mainline: v5.9-rc5
Git-commit: f86b31c6a28f06eed3f6d9dc958079853b0792f1
References: bsc#1170774

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")
