RDMA/bnxt_re: Refactor bnxt_re_create_cq()

Browse source

Some applications may allocate dmabuf based memory for CQs. To support
this, update the existing code to use SZ_4K to specify supported HW
page size for CQs, as we support only 4K pages for now.
Call ib_umem_find_best_pgsz() to ensure umem supports this requested
page size. A helper function includes these changes.
