In older target we may not receive gsi interrupt while
stopping the channel in first retry, so we inject dma
1B packet while retrying. We were observing crash during
stop channel as we were reading channel current state
only after interrupt recieved. Now reading channel
current state in case we not recieved interrupt for
older target.

will receive the IEOB interrupt and xfer pointer will be overwritten
because of this observing the gsi/sys len stats are not matching and
buffers won't be replinished properly leading to HW stall.
To avoid this process all data in polling context, gsi/sys len
