staging: rtl8188eu: fix interface sanity check
commit 74ca34118a0e05793935d804ccffcedd6eb56596 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: c2478d39076b ("staging: r8188eu: Add files for new driver - part 20")
Cc: stable <stable@vger.kernel.org> # 3.12
