refactoring: remove exceptions from space_def_new_from_tuple

space_def_new_from_tuple is used in on_replace_dd_space therefore
it has to be cleared from exceptions. Now it doesn't throw any
more. It means we also need to clear from exceptions it's
subsidiary functions: space_opts_decode, field_def_decode &
space_format_decode. Their usages are updated.
