[Fix] When connected SOftAP goes out of range, AP sate was stuck at Association.

[Fix] When connected SOftAP goes out of range, AP sate was stuck at Association.

This patch fixes the scenario when connected SoftAp goes out of range.
In this case, the profile_info is NULL, due to which state changed callback
was not notified to application.

Below are the test application logs for above mentioned scenario:-

sh-3.2# /usr/bin/wifi_manager_test
