[PATCH v2 1/3] staging/usbip: add uapi header to export usbip kernel interfaces

[Shuah Khan]

usbip userspace has duplicated enum definition to report usbip device
status maintained by the kernel. Adding an usbip uapi header file will
define the kernel - userspace interface for this device status. This
new uapi file is added under usbip/uapi to keep the staging tree code
self-contained. When usbip moves to mainline drivers, this file should
be moved under uapi/linux
