radeonsi: emit framebuffer state after allocating cmask

radeonsi: emit framebuffer state after allocating cmask

tex->cmask_base_address_reg and tex->cb_color_info are used in
si_emit_framebuffer_state so we have to re-emit the state when
they're modified.

It's not done in si_alloc_separate_cmask because it cannot
update framebuffer.dirty_cbufs.
