Hangbin Liu e396694055 tools: ynl: avoid print_field when there is no reply 
When request a none support device operation, there will be no reply.
In this case, the len(desc) check will always be true, causing print_field
to enter an infinite loop and crash the program. Example reproducer:

  # ethtool.py -c veth0

To fix this, return immediately if there is no reply.
