Jack Wang 93b1f29de7 RDMA/cma: resolve to first active ib port
When we try to resolve a dest addr, if we don't give src addr,
cma core will try to resolve to our source ib device automatically.
The current logic only checks if a given port has the same
subnet_prefix as our dest, which is not enough if we use default
well known subnet_prefix on our active port, as it will be the same
as the subnet_prefix on inactive ports and we might match against
an inactive port by accident.  To resolve this, we should also check
if port is active before we resolve it as a suitable src address for
a given dest.
