radv: Use the correct channel for alpha in resolve srgb conversion.
The argument here is a bitmask, so the old code selected .xy, which
got silently truncated to .x when constructing the vec4 from components,
instead of using .w.
Fixes: 588185eb6b7 "radv/meta: add srgb conversion to end of resolve shader."
