[PATCH i-g-t v2 2/3] lib/igt_device_scan: change device list variable visibility

["Zbigniew Kempczyński" <zbigniew.kempczynski@intel.com>]

In commit: 2e8f3e06fb (tests/xe_evict|exec_threads: Use fd reopen
to avoid corrupting global data) I simply changed tests which
corrupted device list global variable. i915 didn't use opening
devices in multithreaded tests but this changed with xe.

Device scan is now unconditional so we may change device list
variable visibility to TLS. With this reverting of above commit
should be safe (but I'm not sure is it worth to do this).
