Sagar Bijwe d32128440d nvs_flash: Detect key partition as uninitialised even if encrypted by bootloader
Currently, only erase operation performed by the application leads
to detection of NVS key partition as uninitialised. This change
adds additional checks for detecting partition as uninitialised,
when device boots first time right after encryption by bootloader.
