qcacld-3.0: Add ini to retain the NOL across reg domain change

Currently driver sets the NOL state of the channels to false
on every regulatory updated, which indicates the channel is
not in NOL. Which may lead to some issues where the channel
is actually in NOL but host treats it as non-NOL channel.

Ideally NOL list should be maintained throughout the driver
lifetime and across the regulatory changes.

To address this issue add a logic to not update the NOL state
of the channels whenever the regulatory update is received.
