qcacmn: Fix regression from DP init-deinit path changes

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.
