With the newly introduced BLM enhancement, APs may get enlisted
and sent to FW for (re)assoc restraint. However, the FW side
AP restraint is only required when LFR3 is enabled.
With LFR2, no FW side AP (re)assoc restraint is required and all
actions will be done within driver code.
Use LFR3 specific conditional macro to enclose all the code
needed for sending reject AP list to FW.
