Acquire wakelock to handle the case where APP's send

aborted and APP will not get scan result and will not connect.

Currently the driver calculates the nss score
based upon the max capability of the AP, and not the
hw_mde config which would be there after connection
for example, the driver calculates the score for a
2x2 11n AP, and 1x1 VHT (11ac) AP, it connects to the
11n AP in 1x1 mode, if a concurrent connection is
present, which affects throughput
Fix is to check whether the current AP channel results
in DBS or not, if yes then change the NSS to 1 instead of
2

Repeater AP failed to associate to Root AP with
hidden ssid in DFS channel.
Normally probe request is sent in passive channels if beacon
from AP is found. With strict passive scan, probe request is
not sent in passive channels even after beacon is found in that
channel.
If AP is configured in hidden ssid, Client/STA does not get the
Probe Response and thus, no SSID information is present in the
scan table to start authentication.
To overcome this, user needs to set the desired {BSSID, SSID} pair,
Example: Desired pair = {00:03:7F:AA:BB:CC, MOON1},
so that when driver receives a beacon it compares the
BSSID and updates the SSID field to update the scan table.
In general, we already set the ssid in sta configuration
But in this case, we also need to configure BSSID of the hidden AP.
This can be configured through iwpriv cmd.
Example: iwpriv athx conf_bssid 11:03:7F:46:03:17

first driver calculates qbss percentage and set qbss score accordingly
and when current RSSI is weaker than or equal to good RSSI threshold

when current RSSI is less than good RSSI threshold.

Currently bool is used to check if scan node is active or not, and
if it is active the deletion can happen. Now if two thread tries to
delete the same node at same time, the first one to get the node
will delete the node and set the active bool to false. If the
delete operation leads to node being freed, the 2nd thread when gets
the lock tries to check the bool, if node is active and then return
if node is not active.
Now if before the 2nd thread check the bool, the memory is reallocate
and the byte pointing to the bool is overwritten with non-zero value
the 2nd thread will assume that node is still active and try to delete
and access an already freed node.
To fix this use cookie instead of bool to check if scan node is active.
