media: flexcop-usb: fix endpoint type check
commit 763679f0eeff0185fc431498849bbc1c24460875 upstream.
Commit d725d20e81c2 ("media: flexcop-usb: sanity checking of endpoint
type") tried to add an endpoint type sanity check for the single
isochronous endpoint but instead broke the driver by checking the wrong
descriptor or random data beyond the last endpoint descriptor.
Make sure to check the right endpoint descriptor.
