ASoC: rt5670: Remove unbalanced pm_runtime_put()
[ Upstream commit 6c900dcc3f7331a67ed29739d74524e428d137fb ]
For some reason rt5670_i2c_probe() does a pm_runtime_put() at the end
of a successful probe. But it has never done a pm_runtime_get() leading
to the following error being logged into dmesg:
rt5670 i2c-10EC5640:00: Runtime PM usage count underflow!
Fix this by removing the unnecessary pm_runtime_put().
