exynos: fimc-is: correct error handling of flite
This patch corrects error handling of flite driver.
With existing error handing, all remaining video frames will
be corrupted if one frame v-blank error is occured because flite
just return with error message without clearing DMA path.
In order to prevent this case, we have to clear DMA path
even if 1-frame v-blank error is occured.
