ASoC: dapm: Fix NULL pointer dereference when registering card with widgets
Commit 0bd2ac3dae74 ("ASoC: Remove CODEC pointer from snd_soc_dapm_context")
introduced regression to snd_soc_dapm_new_controls() when registering a card
with card->dapm_widgets set. Call chain is:
snd_soc_register_card()
-> snd_soc_instantiate_card()
-> snd_soc_dapm_new_controls()
-> snd_soc_dapm_new_control()
Null pointer dereference occurs since card->dapm context doesn't have
associated component. Fix this by setting widget codec pointer
conditionally.
