[PATCH 2/3] qcam: viewfinder_gl: Drop duplicate glClearColor()

[Laurent Pinchart]

There's no need to call glClearColor() twice before drawing any GL
content. Drop the first call. This doesn't introduce any functional
change.

While at it, pass floats instead of doubles to glClearColor(), as
required by the function.
