Fixed multiple enums declaration with _prefix/_suffix

enum is broken when multiple values and `_prefix/_suffix: true` options
are passed.
Because the `enum_prefix/enum_suffix` variables are overwritten from `true` to
`name` during the first loop, and one should return `true` at the second loop, got already overwritten.
