discover_bdevs previously took a port number for the RPC service, but
after commit 6bef902ca5 ("rpc: add default UNIX domain socket listen
address"), running rpc.py with just a -p (port) parameter doesn't have
the expected effect, since the default server_addr is now a UNIX domain
socket path, and the port is ignored.
Change discover_bdevs to accept a socket path instead of a port number
to fix the issue for the vhost/initiator test; no other callers use the
disover_bdevs rpc_port argument, so this is the only instance that needs
to change.
