[cogl] Fix handling of binding errors when uploading a full texture

    Fix handling of binding errors when uploading a full texture
    
    Both the texture drivers weren't handling errors correctly when a
    CoglPixelBuffer was used to set the contents of an entire texture.
    This was causing it to hit an assertion failure in the pixel buffer
    tests.
