[ Upstream commit 3d70e0fb0f289b0c778041c5bb04d099e1aa7c1c ]

In bnxt_qplib_alloc_init_hwq(), while allocating memory for PDE table
driver incorrectly is using the "pg_size" value passed to the function.
Fixed to use the right value 4K. Also, fixed the allocation size for
PBL table.

Fixes: 0c4dcd602817 ("RDMA/bnxt_re: Refactor hardware queue memory allocation")
