media: platform: s3c-camif: Fix runtime PM imbalance on error

Browse source

pm_runtime_get_sync() increments the runtime PM usage counter even
when it returns an error code. Thus a pairing decrement is needed on
the error handling path to keep the counter balanced.

Also, call pm_runtime_disable() when pm_runtime_get_sync() returns
an error code.
