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.
