The underlying IMD function already returns an integer which indicates
success or failure.
This removes the need to have initialized variables that need to be
checked for NULL later. In some cases this actually adds the appropriate
check for returned values.
Dying is appropriate if cbmem is not found as it is essential to the
bootflow.
