If the connected monitor is configured and then legacy STA is trying to
associate to Access point, check is enforced to reject the connection
request if STA + Monitor concurrency is in place.
Legacy STA + monitor mode is not allowed, whereas Legacy STA +
connected monitor should be allowed.
Hence, Fix this issue by checking for STA + Monitor mode concurrency
only if local_packet_capture (Connected monitor) is not enabled.
