media: iguanair: fix endpoint sanity check



Make sure to use the current alternate setting, which need not be the
first one by index, when verifying the endpoint descriptors and
initialising the URBs.

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.
