[PATCH xserver 8/8] dix: Hush an almost certainly bogus warning

[Adam Jackson]

../dix/getevents.c: In function ‘transformAbsolute’:
../dix/getevents.c:1195:28: warning: ‘oy’ may be used uninitialized in this function [-Wmaybe-uninitialized]
     struct pixman_f_vector p = {.v = {*x, *y, 1} };
                            ^
../dix/getevents.c:1234:22: note: ‘oy’ was declared here
     double x, y, ox, oy;
                      ^~

This one is truly special. Even though both ox and oy are set and read
along the same paths, only oy is marked for this warning! Initializing
just oy = 0.0 fixes it entirely, but let's not make a weird thing
weirder.
