intel/isl: Remove tiling checks from choose_msaa_layout
We already do those checks in filter_tiling. There's no good reason to
repeat them in choose_msaa_layout. If anything they should have been
asserts and not "return false" checks. Also, this check was causing us to
outright reject multisampled HiZ surfaces which wasn't intended.
