valentyusb: eptri: don't double-advance read buffer
Due to an error, we were double-advancing the FIFO buffer. The end
result was that the second half of most reads were getting ignored.
This wasn't found during earlier testing because only 64-byte buffers
were tested.
This corrects this error by avoiding double-advancing the buffer.
