usb: musb: cppi41: fix condition to call cppi41_trans_done().
connect AR9271(USB wifi) to AM335x, and send a flood ping from Mac OSX,
AR9271 is stopped.
on USB bus, the following occurs.
- OUT transaction is ACKed (NYET).
- IN transaction is ACKed (512bytes).
- PING-NAK transaction is continued for about 2 seconds (AR9271 timeout?).
In current imprementation, IN-transaction is not completed because it
checks the empty of TX-FIFO in cppi41_dma_callback().
As a result, communication to AR9271 stops.
This patch modified to check the empty of TX-FIFO only when OUT-transaction.
