radv: fix disabling logic op for srgb/float formats when blending is enabled
The Vulkan spec says:
"If logicOpEnable is VK_TRUE, then a logical operation selected by
logicOp is applied between each color attachment and the
fragment’s corresponding output value, and blending of all
attachments is treated as if it were disabled. Any attachments
using color formats for which logical operations are not supported
simply pass through the color values unmodified."
When logic op and blending are both enabled, logic op takes precedence
and values should be passed through unmodified. Also RB+ shouldn't
have any effects when blending is disabled.
Fixes new VKCTS coverage dEQP-VK.pipeline.*.logic_op_na_formats.*.
