ASoC: soc-core: Hold client_mutex around soc_init_dai_link()
soc_init_dai_link() calls soc_find_component() which needs
to be within client_mutex lock. Add client_mutex lock around
soc_init_dai_link() in snd_soc_register_card() to avoid
lockdep warning.
Fixes: 8780cf1142a5 ("ASoC: soc-core: defer card probe until all component is added to list")
