RDMA/rxe: Fix inaccurate constants in rxe_type_info
[ Upstream commit 3a73746b267e5c6a87c9ad26f8c6a48e44da609c ]
ibv_query_device() has reported incorrect device attributes, which are
actually not used by the device. Make the constants correspond with the
attributes shown to users.
Fixes: 3ccffe8abf2f ("RDMA/rxe: Move max_elem into rxe_type_info")
Fixes: 3225717f6dfa ("RDMA/rxe: Replace red-black trees by xarrays")
