ALSA: Don't assume i2c device probing always succeeds
commit 18c4078489fe064cc0ed08be3381cf2f26657f5f upstream.
The client->driver pointer can be NULL when i2c-device probing fails
in i2c_new_device(). This patch adds the NULL checks for client->driver
and return the error instead of blind assumption of driver availability.
