Subject: [PATCH 2/2] HID: usbhid: Add HID_QUIRK_NO_INIT_REPORTS for Oculus Rift CV1

When plugging in an Oculus Rift CV1 HMD, it takes a long time until the hidraw
devices appear, specifically two control transfers time out querying the HID
report descriptors:

    $ echo 1 > /sys/module/hid/parameters/debug

    usb 1-3.1: new full-speed USB device number 11 using xhci_hcd

    usbcore: registered new interface driver usbhid
    usbhid: USB HID core driver

These timeouts disappear when setting HID_QUIRK_NO_INIT_REPORTS. The hidraw
devices appear quickly and are functional.
