Commit 3f230e0e30 dropped the fix of 64ff18b65 to fallback to the whole
MTD size in case no decrypted-size or decompressed-size was given.
This restores the changes and uses the MTD size in case no property is
set. This avoids compatibility issues when an older SWU will be
installed using a newer SWUpdate.
