Honggang LI e4ee11c00d RDMA/rtrs: Fix clt_path::max_pages_per_mr calculation 
[ Upstream commit 43bd09d5b7 ]

If device max_mr_size bits in the range [mr_page_shift+31:mr_page_shift]
are zero, the `min3` function will set clt_path::max_pages_per_mr to
zero.

`alloc_path_reqs` will pass zero, which is invalid, as the third parameter
to `ib_alloc_mr`.
