ASoC: rt5514: Avoid relying on uninitialized "val" value

In rt5514_i2c_probe() if the regmap_read(RT5514_VENDOR_ID2) fails then
"val" may be left as uninitialized.  Current code relies on "val" not
being RT5514_DEVICE_ID, but that's potentially unsafe.

Let's check for errors from regmap_read() and also explicitly init the
value do we're not passing a possibly uninitialized int to printk.
