PM: runtime: clk: Fix clk_pm_runtime_get() error path
commit 64c7d7ea upstream. clk_pm_runtime_get() assumes that the PM-runtime usage counter will be dropped by pm_runtime_get_sync() on errors, which is not the case, so PM-runtime references to devices acquired by the former are leaked on errors returned by the latter. Fix this by modifying clk_pm_runtime_get() to drop the reference if pm_runtime_get_sync() returns an error.
