RDMA/siw: replace redundant ternary operator with just rv

The use of the ternary operator on rv is redundant, rv is
either the initialized value of 0 or a negative error return
code, so it can never be greater than zero, and hence the
zero assignment in ternary operator is redundant. Just return
rv instead.
