[Spice-devel] [PATCH usbredir] usbredirserver: reject empty vendor id in cmd line

[Chen Hanxiao]

From: Chen Hanxiao <chenhanxiao at gmail.com>

Vendor ID 0000 is not a valid ID [1]
But we could pass it from cmd:
  usbredirserver :abcd
   or
  usbredirserver 0000:abcd

Which will pass a 0000 vendor id to usbredirserver.

This patch will check this senario.
