USB: usbfs: export the URB_NO_INTERRUPT flag to userspace

This patch (as1079) cleans up the way URB_* flags are exported in
usbfs.

	The URB_NO_INTERRUPT flag is now exported (this is the
	only behavioral change).

	USBDEVFS_URB_* macros are added for URB_NO_FSBR,
	URB_ZERO_PACKET, and URB_NO_INTERRUPT, making explicit the
	fact that the kernel accepts them.

	The flag matching takes into account that the URB_* values
	may change as the kernel evolves, whereas the USBDEVFS_URB_*
	values must remain fixed since they are a user API.
