[PATCH v2] Xext: Fix a memory leak on GE client disconnect.

[Rami Ylimaki]

Add a call to dixRequestPrivate to inform dixFreePrivates that memory
allocated in GEClientCallback should be released when client
disconnects. Otherwise there is a leak of sizeof(GEClientInfoRec) for
every client connect/disconnect.

Also remove the explicit allocation and let GEGetClient /
dixLookupPrivate do it. This makes GEClientCallback similar to the
other extension callbacks.
