When a msdu scattered across multiple nbufs is received
in REO2SW ring and the remaining nbufs are not yet
available in the ring, loop in dp_rx_process is exited
without resetting the invalid bit in the ring desc cookie.
This will result in an incorrect assertion failure when
the same entry is processed the next time.
Fix is to reset the invalid bit in ring desc cookie
when the loop is exited in the above msdu scattered
scenario.
