Fix Upgrade in LogstoreFamily

[shosseinimotlagh]

Maintaining Compatibility for different versions
In previous versions of AM image, i.e., AM20, m_metablk_name was populated with LogDevFamily. In the recent, m_metablk_name had been changed to LogStoreFamily which results in broken recovery procedure from older versions. In this PR I revert it back that upgrading from AM -20 to AM21 will be possible.
