HID: bring back possibility to specify vid/pid ignore on module load
When hid quirks were converted to specialized driver, the HID_QUIRK_IGNORE has been moved completely, as the hid_ignore_list[] has been moved into the generic code. However userspace already got used to the possibility that modprobing usbhid with 'quirks=vid:pid:0x4' makes the device ignored by usbhid driver. So keep this quirk flag in place for backwards compatibility. Signed-off-by: Jiri Kosina <jkosina@suse.cz>
