qcacld-3.0: Add ini wlm_latency_reset_on_disconnect

Currently, the WLM mode could be recovered after disconnection
or interface down/up about random MAC feature. Since some OEMs
have different mechanisms to config WLM mode on their framework
implementation and don't expect recovering the WLM mode.

So add logic to set default WLM mode when disconnection happens.
And add ini wlm_latency_reset_on_disconnect to differentiate
the implementation in driver. By default
wlm_latency_reset_on_disconnect is false.
