ASoC: soc-core: check ops & auto_selectable_formats in snd_soc_dai_get_fmt() to prevent dereference error

Smatch reported an issue that "ops" could be null (see
line 174) where later "ops" is dereferenced to extract
the dai fmts, also auto_selectable_formats can also be
null.

Add a proper null check before accessing both the ptrs
to ensure a safe execution.
