The EP0 code routinely ignores interrupt at end of the data phase because of
musb_g_ep0_giveback() resetting the state machine to "idle, waiting for SETUP"
phase prematurely.

This fixes most of the unhandled gadget interrupts that generic_interrupt() and
davinci_interrupt() have been hiding from user by faking their result and only
emitting 5th level debug message (for what is clearly an error).
