USB: serial: io_edgeport: fix epic endpoint lookup
Make sure to use the current alternate setting when looking up the
endpoints on epic devices 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: 6e8cf7751f9f ("USB: add EPIC support to the io_edgeport driver")
