media: dib0700: fix rc endpoint lookup

2020-02-24T15:24:21Z

Make sure to use the current alternate setting when verifying the interface descriptors to avoid submitting an URB to an invalid endpoint. Failing to do so could cause the driver to misbehave or trigger a WARN() in usb_submit_urb() that kernels with panic_on_warn set would choke on.
