Xming,Cygwin/X: Fix crashes when using the DirectDraw '-refresh rate-in-Hz' option in -fullscreen (#11128)

Browse Source 
fd.o bugzilla #11128

Fix crashes when using the '-refresh rate-in-Hz' option in -fullscreen mode and using a DirectDraw engine.
On failure (typically 0x80004001 DDERR_UNSUPPORTED), use the default refresh rate for the driver, instead of the
entered value.

Also fix some nearby error reporting
