ASoC: Only deregister AC97 dev if it's name was not "AC97"
The commit 14fa43f53ff3a9c3d8b9662574b7369812a31a97 ("ASoC: Only
register AC97 bus if it's not done already") added a condition for
calling of soc_ac97_dev_register() but not added for calling of
soc_ac97_dev_unregister(). This patch adds same condition for
soc_ac97_dev_unregister(). Without this fix, kernel crashes when
unloading an asoc driver.
