X-Git-Tag: accepted/tizen/7.0/unified/20240925.162126~1

Check if ckmc_get_data() provides NULL value

There are cases where ckmc_get_data() provides NULL value
due to a DB issue used by key-manager.
This causes passphrase decryption to fail and causes wifi connection failure.
Code has been added to check for this situation.
