gif loader: show the current frame image if getting row is failed 

Summary:
Change-Id: I17c79f89550e9a758a532babd55826b3c7ad2810

To show gif animation smoothly, we keep the current frame even if getting line is failed.
Currently,  the frame image will be freed if getting gif line is failed and this makes the frame drop.
