- Fixed uninitialized variable in case GL_MAX_VERTEX_SHADER_STORAGE_BLOCKS does not exist.

Browse source 
Old graphics, like mine (Intel Sandybridge Mobile, GL 3.0 Mesa) do not support this, therefore most of the time RFL_SHADER_STORAGE_BUFFER wasn't unset (I found no consequence of this on my machine, but better safe than sorry).

Found out by Valgrind.
