Jeff Squyres 202f64868c btl openib: only initialize CPCs if there are devices to use
Defer initializing the CPCs until we know that we have devices/ports
to use.  This both prevents some useless work at startup when there
are no devices/ports to use, and also prevents librdmacm complaining
that there are no verbs-capable RDMA devices available (e.g., if a
Cisco usNIC device is present, but does not present a verbs RDMA
interface).
