[PATCH] Update lastDeviceEventTime in XResetScreenSaver

[Julien Cristau]

From: Lubos Lunak <l.lunak at suse.cz>

After xserver commit 6b5978dcf1f7ac3ecc2f22df06f7000f360e2066
(Do not reset lastDeviceEventTime when we do dixSaveScreens)
applications using XResetScreenSaver() no longer prevent the KDE
screensaver from activating, which uses XScreenSaverQueryInfo() to
detect the idle time and activates after a specified timeout. After this
commit there appears to be no way to detect that XResetScreenSaver() has
been used (the IDLE timer is presumably affected as well).
