Jon TURNEY 09fd010902 Cygwin/X: DirectDraw engines shouldn't try to blit if the surface wasn't allocated ...

Fix winShadowUpdateDD(|NL) so we don't try to blit to primary surface if it didn't get allocated

(Intel drivers, in particular, seem to like to issue a WM_DISPLAYCHANGE during a suspend/resume
cycle, but not allow surface to be allocated right then)

Also:
Use winReleasePrimarySurfaceShadowDD(|NL) in winFreeFBShadowDD(|NL) rather than open coding it
Don't mess about recreating surface if we're going to resize it anyhow
