Staging: USB-IP code cleanup

Browse Source 
This includes fixes for all of the legit checkpatch.pl errors and
warnings.  I have also included several of the suggestions from the
linux-kernel mailing list when the USB-IP code was first added.

@ -6,7 +6,7 @@ config USB_IP_COMMON
This enables pushing USB packets over IP to allow remote
machines access to USB devices directly. For more details,
and links to the userspace utility programs to let this work
properly, see http://usbip.naist.jp/
properly, see http://usbip.sourceforge.net/.
To compile this driver as a module, choose M here: the
module will be called usbip_common_mod.
