OpenGL Renderer: Fix issues that would throw a GL error.

- glTexParameteri() with GL_TEXTURE_2D_MULTISAMPLE throws INVALID_ENUM when trying to assign a sampler-related state, so these calls have been removed.
- glMapBufferRange() throws GL_INVALID_OPERATION if the buffer size is 0, so check for this condition first.
