Fixes a regression from bb2e02ab.

This appear to be introduced with commit 12f73ed9.

When This->stride is negative (bottom up image) it converts the multiplication to an UINT.
Thus causing the pointer to be incorrect when y > 0.

And only refresh the list if the device handle isn't known.

OpenImageViewer calls these functions when triggering the image
properties menu.

Restore display settings to the ones in the registry when CDS_FULLSCREEN
is used in ChangeDisplaySettings().

We have to invalidate the current mode cache if there are pending
RRNotify events. The performance hit on EnumDisplaySettingsExW is
around 7%.

Also call X11DRV_DisplayDevices_RegisterEventHandlers in x11drv_init.
Otherwise, RRNotify events will only be handled in the explorer process.
