RDMA/ucma: Allow resolving address w/o specifying source address
The RDMA CM will select a source device and address by consulting
the routing table if no source address is passed into
rdma_resolve_address(). Userspace will ask for this by passing an
all-zero source address in the RESOLVE_IP command. Unfortunately
the new check for non-zero address size rejects this with EINVAL,
which breaks valid userspace applications.
Fix this by explicitly allowing a zero address family for the source.
