radeonsi: make gl_SampleMaskIn = 0x1 when MSAA is disabled
gl_SampleMaskIn is 1 when R_028BE0_PA_SC_AA_CONFIG is 0, so this commit
rework the conditions
controlling this register.
Before it was set if the sctx->framebuffer had a sample count > 1.
Now we still require this condition, but we also need either:
- GL_MULTISAMPLE to be enabled
- to be executing an operation that doesn't depends on GL state using
u_blitter.
This fixes the arb_sample_shading/sample_mask piglit tests on radeonsi.
