[PATCH xinput 3/5] Don't leak output_info

[Peter Hutterer]

This inverts the logic to have a more obvious flow for freeing the
output_info.

==26716== 1,161 bytes in 8 blocks are definitely lost in loss record 5 of 7
==26716==    at 0x4A074CD: malloc (vg_replace_malloc.c:236)
==26716==    by 0x395D804ABA: XRRGetOutputInfo (in /usr/lib64/libXrandr.so.2.2.0)
