Early stop scan is a feature for roaming to stop the scans at
an early stage as soon as we find a better AP to roam. This
would make the roaming happen quickly.
Apart from sending the configuration items, the host also
has to send down the channel list in a sorted order
to optimize the scans and meet the requirement of this
feature.
This feature is currently applicable only to roaming
scans. However the sorted order of scan list will be
the same used by all the scans.

- Kill wlan_tasklet before freeing TLshim free queue. This can avoid

This is to avoid corner cases that while FW crashes, disconnection is
happening or disconnection fails because of FW crash, the HDD state is
changed from connected to disconnecting/disconnected.
