ASoC: core: Don't set "(null)" as a driver name
Commit 22de71b ("ASoC: core - allow ASoC more flexible machine name")
writes "(null)" to driver name string in struct snd_card if card->driver_name
is NULL. This causes segmentation faults with some user space ALSA utilities
like aplay and arecord.
Fix this by using the card->name if no driver name is specified.
