** [tickets:#294] libjaylink fails to discover devices when network is down and
J-Link S/N is specified**

This issue is rather related to libjaylink library but I was unable to find any
public libjaylink bug tracker so I'm posting the issue here.
libjaylink is unable to find the probe by it's serial number when all network
interfaces are down/disconnected. This makes it impossible to use OpenOCD on
offline machines with several JLink probes connected.
Steps to reproduce:
Put you computer offline (disconnect all Ethernet cables and turn WiFi off)
Run the following script:
~~~
source [find interface/jlink.cfg]
jlink serial <your_serial_here>
source [find target/psoc6.cfg]
init
exit
~~~
Observe the following error:
~~~
Error: Failed to send discovery message.
Error: TCP/IP device discovery failed.
Error: jaylink_discovery_scan() failed: input/output error.
~~~
I've tracked the issue down to *discovery_tcp_scan* function which fails on
offline machines (which is OK) but this error is treated as fatal in
*jaylink_discovery_scan* so whole device discovery fails.
