Problem:
During wifi up/down, dfs_init_precac_list() is called to initialize
the precac list without de-allocating the previously allocated memory.
This leads to a memory leak.
Solution:
Deinit the allocated memory before initializing the precac list.

2) Move random channel filtering flags from dfs_internal.h to

2) Use dfs_info for important prints such as CAC timeout,
NOL timeout, enable/disable radar etc.
3) For everything else use dfs_debug macro.

Reverse CSA:
===========
Problem:
When Repater detects the RADAR, it sends RCSA to RootAP and
immediately switches to a new channel without waiting for CSA
from Root AP.
Expected behaviour:
When Repeater detects the RADAR, if uplink is present then it sends
RCSA to RootAP and waits for 2secs to receive CSA. If Repeater
does not receive CSA in 2sec, choose a random channel and
bring up the AP vap.
Solution:
In Repeater, if RCSA is sent successfully to RootAP then wait for
2secs to receive CSA from Root else choose a random channel and
bring up the vaps.

In Repeater AP scenario, when STA vap starts scan, it calls this
registered DFS callback function to get the AP CAC status. If the
AP vap is performing CAC, STA vap does not start SCAN.

Analysis:
dfs_nol_timer_cleanup() calls dfs_nol_update(), which internally
calls a legacy function to update the scan channel list and sends
a WMI command to FW. However, from WIN side dfs_nol_timer_cleanup()
is also called after target stop, which leads to a kernel panic.
Solution:
Call dfs_nol_update() prior to target stop.
Initalize precac channel list during dfs reset.

Currently only one connection information corresponding to the
provided mode is deleted and restored, which causes channel
selecting failure in DFS testing with AP+AP concurrency mode.
When radar is found in AP+AP concurrency mode, a new valid channel
should be selected. Before selecting the channel, all existing
connection information of SAP mode should be deleted, otherwise
no valid channel can be selected.
All the connection information corresponding to the provided mode
should be deleted and restored.

As part of DFS component destroy, "ic" is accessed to reset
NOL list and PRECAC channel list, but "ic" is already deleted
as part of MLME component destroy. And therefore invalid memory
access happens.
