[COMMON] media: scaler: fix power-off bug for scaler

There is a possibility which g2d block power off
while scaler is running. A scaler is in the g2d block.
In interrupt handler, rm_runtim functions, pm_runtime_get
or pm_runtime_put, are uesed as asynchronous mode.
But since a wating job can be called in interrupt handler,
g2d block power is turned off due to the asyncchronous
pm_runtime_put function while the job is performing.
Therefore, the pm_runtime_put should be called after
the wating job which performs in irq handler is done.
