[PATCH] tests/intel/xe_drm_fdinfo: Do not end NULL xe_cork

[Jonathan Cavitt <jonathan.cavitt@intel.com>]

An earlier commit prevented the execution of the xe_cork_destroy
function when the xe_cork is not initialized via xe_cork_create in
xe_drm_fdinfo.  This must also be done with the xe_cork_sync_end
function in some places.

Fixes: 2feb1d67 ("lib/xe/xe_spin: move the spinner related functions to lib")
Closes: https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/3869
