Subject: [PATCH v2 3/3] PM / devfreq: exynos-bus: Fix the wrong return value

This patch fixes the wrong return value. If devfreq driver requires the wrong
and non-available governor, it is fail. So, this patch returns the error
insead of -EPROBE_DEFER.

Fixes: 403e0689d2a9 ("PM / devfreq: exynos: Add support of bus frequency of
		      sub-blocks using passive governor")
