Alan Coopersmith 5a8effe1e7 Xext/sync: Avoid dereference of invalid pointer if malloc() failed 
Reported incorrectly in https://gitlab.freedesktop.org/xorg/xserver/-/issues/1817 as:

xwayland-24.1.6/redhat-linux-build/../Xext/sync.c:2835:33: acquire_memory: allocated here
xwayland-24.1.6/redhat-linux-build/../Xext/sync.c:2843:12: danger: ‘priv’ leaks here; was allocated at [(30)](sarif:/runs/0/results/5/codeFlows/0/threadFlows/0/locations/29)

but the "leak" is really saving the pointer in an uninitalized pointer in
a structure that was already freed when the malloc of the SysCounterInfo
struct failed in SyncCreateSystemCounter(), because it returned the address
of the freed struct instead of NULL to indicate failure.
