Subject: intel/isl: Fix up asserts in calc_phys_level0_extent_sa

The assertion that a format is uncompressed in the multisample layouts
isn't quite right.  What we really want to assert is that the format
supports multisampling which is a bit more complicated query.  We also want
to assert that it has a block size of 1x1 since we do nothing with the
block size in the phys_level0_sa assignment.
