Remove 3 DCHECK failure expectations in virtual/layout_ng_block_frag

r793989 crrev.com/c/2332083 caused a test in `virtual/
layout_ng_block_frag` to hit DCHECK failure in
|NGInlineCursor|, and probably caused two flakes in
crbug.com/1112237 and crbug.com/1112289.

r795011 crrev.com/c/2313736 supports block fragmentation in
|NGInlineCursor|. This patch removes these DCHECK failiure
expectations.
