Subject: [PATCH] Xext: SProcSyncCreateFence needs to swap drawable id too

Otherwise it causes the server to return BadDrawable giving a
byte-swapped resource id instead of the real id the client sent.

Reported-by: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=69762
Fixes: 397dfd9f8 ("Create/Destroy/Trigger/Reset/Query Fence Sync objs")
