RDMA/erdma: initialize ret for empty receive WR lists

erdma_post_recv() returns ret after walking the receive work request list.
If the caller passes an empty list, the loop is skipped and ret is not
assigned.

Initialize ret to 0 so an empty receive work request list returns success
instead of stack data.
