MCL DP initialization path is running into issues due to change I5732453f617bdc16995fda916b645c41845c3ecb. Fix the same. Move flow control lock variables to re-use region. This is needed since flow control deinit happens in dp_soc_detach, while in dp_soc_deinit, the soc memory is being partially reset. De-init HTT memory in dp_soc_deinit and free HTT handle in dp_soc_detach. The existing code was not freeing HTT packets for MCL case and freeing the HTT handle twice.
