USB: option Add blacklist for ZTE K3765-Z (19d2:2002)

The funtion option_send_status times out when sending USB messages
to the interfaces 0, 1, and 2 of this UMTS stick. This results in a
5s timeout in the function causing other tty operations to feel very
sluggish.

This patch adds a blacklist entry for these 3 interfaces on the ZTE
K3765-Z device.

I was also able to reproduce the problem with v2.6.38 and v2.6.39.

This is very similar to a problem fixed in
