Revert "RDMA/cma: Simplify rdma_resolve_addr() error flow"
This reverts commit 219d2e9dfda9431b808c28d5efc74b404b95b638.
The call chain below requires the cm_id_priv's destination address to be
setup before performing rdma_bind_addr(). Otherwise source port allocation
fails as cma_port_is_unique() no longer sees the correct tuple to allow
duplicate users of the source port.
rdma_resolve_addr()
cma_bind_addr()
rdma_bind_addr()
cma_get_port()
cma_alloc_any_port()
cma_port_is_unique() <- compared with zero daddr
This can result in false failures to connect, particularly if the source
port range is restricted.
