rG13e9b4e5e21d: apple_bce: ignore duplicate TRANSFER_REQUEST in STATUS state

Summary

Since the host initiates IN data transfers, the
firmware's own TRANSFER_REQUEST for the same phase arrives after
we've already moved to STATUS state. Ignoring instead of failing
the transfer with USB_ERR_IOERROR.
