ANDROID: usb: send netlink on device config error

When peer is connected to USB-A port there is no notification
to userspace. As a result we don't know when to enable the DbC
on USB-A port. The patch adds netlink notifcation to be sent to
userspace when config error happens. Config error hapens when
two USB hosts are connected and it is a signal to enable DbC.

      when two USB hosts are connected over USB-A port on DUT
