winhlp32: Invalidate scrollbar when changing pages. (Bug 14293)

[Dylan Smith]

Previously the scrollbar was not being shown when clicking on a link to
go to a page with more than a page of text.  This was because winhlp32
was setting up the richedit control with redraw turned off, then
invalidated the client area, which excluded the scrollbar.  Instead I
had the non-client area also invalidated to fix the bug.
