st/mesa: call update_renderbuffer_surface for sRGB renderbuffers, too
st/mesa: call update_renderbuffer_surface for sRGB renderbuffers, too

sRGBEnabled should affect both textures and renderbuffers, so we need
to check/update the pipe_surface format for both.

Fixes, for instance, rendering appearing too bright in wine applications
using sRGB multisample renderbuffers.

NOTE: This is a candidate for the 8.0 branch.
