[Intel-gfx] [PATCH i-g-t 1/3] lib/igt_device_scan: fix dangling pointer

[Matthew Auld]

It looks like the linkto is out of scope:

../lib/igt_device_scan.c: In function ‘igt_device_add_attr’:
../lib/igt_device_scan.c:368:57: warning: dangling pointer ‘v’ to ‘linkto’ may 
be used [-Wdangling-pointer=]
  368 |         g_hash_table_insert(dev->attrs_ht, strdup(key), strdup(v));
      |                                                         ^~~~~~~~~
../lib/igt_device_scan.c:351:22: note: ‘linkto’ declared here
  351 |                 char linkto[PATH_MAX];
