freedreno/a6xx: fix blend all_mrt_write_mask

Fix all_mrt_write_mask when independent_blend_enable is false.
Otherwise, lrz write is always diabled with MRT when
independent_blend_enable is false.  This fixes a 2% perf regression for
multiple gfxbench benchmarks.

Fixes: 0132c22de75 ("freedreno/a6xx: Don't disable LRZ for invalid channels")
