qcacld-3.0: Create lim session for monitor mode for legacy targets

For the latest chipsets because of architecture change the
lim session for monitor mode is not required but for the
older chipsets using the mainline the lim session has to be created.
If the session is not created the channel setting to capture
the packets on the monitor interface fails.

Create the monitor session in lim for older targets.
