USB: idmouse: fix interface sanity checks
commit 59920635b89d74b9207ea803d5e91498d39e8b69 upstream.
Make sure to use the current alternate setting when verifying the
interface descriptors to avoid binding to an invalid interface.
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.
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
Cc: stable <stable@vger.kernel.org>
