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.
