udev: fix SUBSYSTEMS and ATTRS{idVendor} checks

Browse Source 
Rules with a single condition where a parent property is checked with != don't
work properly. E.g.:
  SUBSYSTEMS!="usb", GOTO="end"
or:
  ATTRS{idVendor}!="abcd", GOTO="end"

Instead, we can mix both those previous parent rules and match them:
  SUBSYSTEMS=="usb",ATTRS{idVendor}=="abcd", GOTO="next"
  GOTO="end"
  LABEL="next"
  # Apply rules here
  LABEL="end"

In this case both SUBSYSTEMS and ATTRS conditions apply to the parent usb_device
(idVendor attribute is only available in the usb_device), so they apply to all
ports of the same device.
