Bhargava Chenna Marreddy 5d474ef184 RDMA/bnxt_re: Fix a bug while setting up Level-2 PBL pages
[ Upstream commit 7988bdbbb85ac85a847baf09879edcd0f70521dc ]

Avoid memory corruption while setting up Level-2 PBL pages for the non MR
resources when num_pages > 256K.

There will be a single PDE page address (contiguous pages in the case of >
PAGE_SIZE), but, current logic assumes multiple pages, leading to invalid
memory access after 256K PBL entries in the PDE.

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