[PATCH] RDMA: initialize return values for empty work request lists

[Ruoyu Wang]

erdma_post_recv() and mana_ib_post_send() both return their loop status
variable after walking a work request list. If the caller passes an empty
list, the loop is skipped and the variable is not assigned. Initialize
the return value to 0 for the empty-list success path.
