RDMA/mana_ib: initialize err for empty send WR lists

Browse Source 
mana_ib_post_send() returns err after walking the send work request list.
If the caller passes an empty list, the loop is skipped and err is not
assigned.

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