USB: ipaq: minor ipaq_open() cleanup.
Commit b512504e5671f83638be0ddr085c4b1832f623d3 made ipaq_open() a bit
messy by moving the read urb submission far from its usb_fill_bulk_urb()
call and the comment explaining what it does.
This patch put they together again. Although only compiled tested, should
not break the fix introduced by b512504e5671f83638be0ddr085c4b1832f623d3,
of course.
