Fix call to getImageFormatFeatureBits() in SurfaceVk.cpp
Fix call to getImageFormatFeatureBits() in SurfaceVk.cpp

The function getImageFormatFeatureBits() was recently refactored which
changed its parameters. One call to this function in SurfaceVk.cpp is
underneath a #if ANGLE_ENABLE_OVERLAY though, so it was missed.

This CL updates the call to getImageFormatFeatureBits() with the correct
paramater as well as moves the code outside of the #if and into a normal
conditional to prevent similar issues in the future.
