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.
