USB: io_edgeport: eliminate get_string()
Johan Hovold points out that get_string() is basically just a
re-implimentation of usb_string(). It is also buggy. It does DMA on
the stack and it doesn't handle negative returns from
usb_get_descriptor(). Plus unicode_to_ascii() is a rubbish function and
moving to usb_string() avoids using it.
Let's eliminate get_string() entirely.
