RDMA/bnxt_re: Fix the page_size used during the MR creation

Driver populates the list of pages used for Memory region wrongly when
page size is more than system page size. This is causing a failure when
some of the applications that creates MR with page size as 2M.  Since HW
can support multiple page sizes, pass the correct page size while creating
the MR.

Also, driver need not adjust the number of pages when HW Queues are
created with user memory. It should work with the number of dma blocks
returned by ib_umem_num_dma_blocks. Fix this calculation also.
