RDMA/rxe: Reject unimplemented implicit ODP cleanly

Browse source

rxe advertises ODP but not IB_ODP_SUPPORT_IMPLICIT. The reg_user_mr path
still contained a dead branch that checked the implicit capability and
could never succeed.

Return -EOPNOTSUPP for the implicit ODP address range up front so the
intent is obvious and the unreachable code is gone.
