svga: convert dst format to linear when blending is enabled. 

When blending is enabled, framebuffer colorspace has to be linear.
Previously, we never hit this case because we were not supporting sRGB
drawable. Previous patch added that support.

Tested with mtt glretrace, viewperf, piglit, conform.
