qcam: viewfinder_gl: Keep fragment shader when format doesn't change
When ViewFinderGL::setFormat() is called, the fragment shader is deleted and recreated for the new format. This results in unnecessary shader recompilation if only the size is changed and the pixel format remains the same. Keep the existing shader in that case. The null test for fragmentShader_ can be removed, as if the shader program is linked, the fragment shader is guaranteed to exist.
