CHROMIUM: ASoC: samsung i2s: fix error for codec-plugin

The result of the device tree look-up for the plugin device
was checked against the wrong variable.
As a consequence, if the codec-plugin plugin property is set
to a non-existent value, the kernel will crash at startup instead of
skipping the plugin.

BUG=chrome-os-partner:14489
TEST=boot on Spring with hdmi-audio disabled in the device tree
and see we are longer crashing in i2s plugin probing.
