USB serial: add missing .usb_driver field in serial drivers
This patch (as1443) fixes a bug found in many of the USB serial
drivers: They don't set the .usb_driver field in their
usb_serial_driver structure. This field is needed for assigning
dynamic IDs for device matching.
In addition, starting with the 2.6.37 kernel, the .usb_driver field is
needed for proper autosuspend operation. Without it, attempts to open
the device file will fail.
