[PATCH 2/1] config: let `config_store_data_clear()` handle `value_regex`

["Martin Ågren" <martin.agren@gmail.com>]

Instead of carefully clearing up `value_regex` in each code path, let
`config_store_data_clear()` handle that.

I *think* that it should be ok to `regfree()` after `regcomp()` failed,
but I'll need to look into that some more (and say something about it in
the commit message).
