Creating and update a hash tree involves several RPC commands.
If a power loss occurs during the creation flow, it may result
in a hash tree with an incomplete header and a counter value of 0.
If attempting to read this file subsequently leads to a
TEE_ERROR_CORRUPT_OBJECT error.
Instead of returning TEE_ERROR_CORRUPT_OBJECT, continue the
initialization flow to support subsequent functionality.
