Alan Coopersmith 3cd7892e91 randr: handle -Wanalyzer-null-dereference in ProcRRGetOutputInfo() 
Reported in #1817:
xwayland-24.1.6/redhat-linux-build/../randr/rroutput.c:540:13:
 warning[-Wanalyzer-null-dereference]: dereference of NULL ‘0’

The NULL dereference was only theoretically possible if the sum of
the sizes wrapped around to 0, but this ensures a NULL dereference
won't happen even in that case.
