lockBufferDrawable() can return a null pointer, so it should be checked first.

Why was this never a problem before? Did the semantics of lockBufferDrawable change?

It is WebKit style to put the temp var declaration in the if.

They didn't, it can actually return a null pointer. I don't think it's
the case here anyway but see also bug 114005.
