[GFC] Close updateScrollInfoAfterLayout transaction on GFC early-return
https://bugs.webkit.org/show_bug.cgi?id=315377
<rdar://177732995>
Reviewed by Sammy Gill.
RenderGrid::layoutGrid opens an updateScrollInfoAfterLayout transaction via
beginUpdateScrollInfoAfterLayoutTransaction(), but the modern Grid Formatting
Context (GFC) fast path early-returns before reaching the matching
endAndCommitUpdateScrollInfoAfterLayoutTransaction() on the legacy path.
Mirror the legacy path by calling
endAndCommitUpdateScrollInfoAfterLayoutTransaction()
on the GFC fast path before returning, so the transaction is always balanced
and deferred blocks are flushed at layout completion.
