radv: disable logic op for float/srgb formats

Browse source 
The Vulkan spec says:
    "The application can enable a logical operation between the
     fragment’s color values and the existing value in the framebuffer
     attachment. This logical operation is applied prior to updating
     the framebuffer attachment. Logical operations are applied only
     for signed and unsigned integer and normalized integer
     framebuffers. Logical operations are not applied to floating-point
     or sRGB format color attachments."

Missing VKCTS coverage has been reported.
