RDMA/bnxt_re: Fix a bug while setting up Level-2 PBL pages

In the Linux kernel, the following vulnerability has been resolved:

RDMA/bnxt_re: Fix a bug while setting up Level-2 PBL pages

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.
