i965/gen9: Don't do fast clears when GL_FRAMEBUFFER_SRGB is enabled
When GL_FRAMEBUFFER_SRGB is enabled any single-sampled renderbuffers
are resolved in intel_update_state because the hardware can't cope
with fast clears on SRGB buffers. In that case it's pointless to do a
fast clear because it will just be immediately resolved.
