[ Upstream commit dafa3605fe60d5a61239d670919b2a36e712481e ]
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.
