[usb] Cannot send a zero size packet in IN transaction in USB2.0 core.

Dear Rudolf Usselmann:

     Sorry to disturb you again!
     After test your core carefully, I found your USB2.0 core
cannot send a zero size packet in IN transaction.
     In usbf_idma.v line 299:

if(!rst)			sizd_c <= #1 14'h3fff;
	else
	if(tx_dma_en | tx_dma_en_r)	sizd_c <= #1 size;
	else
	if(siz_dec)			sizd_c <= #1 sizd_c - 
14'h1;
