richedit: Initially disable scrollbars for ES_DISABLENOSCROLL.

Previously after initial window creation of a richedit control with the
ES_DISABLENOSCROLL window style flag the scrollbar would be shown but
not disabled.  This patch fixes this issue by explicitly disabling and
showing the scrollbar.
