Bluetooth: Restarting PM timer during incoming rfcomm data.

During incoming rfcomm data, we were setting the pm mode to
active, thereby stopping timer and never restarting it again.
So Dut was never going to sniff , if the last packet is incoming
packet. Therefore add change to restart the PM timer during incoming
data.
