USB: musb_gadget_ep0: fix unhandled endpoint 0 IRQs, again
Commit a5073b5283
(musb_gadget: fix
unhandled endpoint 0 IRQs) somehow missed its key change:
"The gadget EP0 code routinely ignores an interrupt at end of
the data phase because of musb_g_ep0_giveback() resetting the
state machine to "idle, waiting for SETUP" phase prematurely."
So, the majority of the cases of unhandled IRQs is still unfixed...
