qcacld-3.0: Restore all control config params upon CLEAR_ALL

User might modify the roam control config params through
multiple commands as part of roam control config enable.
Currently, only the params which are modified as part of
SUBCMD_CONTROL_SET command are restored. Restore all of the roam
control config params from the default ini values when the
control config is disabled i.e when the CLEAR_ALL is received.
