    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.
