drm/xe: Fix xe_pt_abort_unbind

Browse Source 
When restoring the children PT entries on a bind failure the incorrect
loop index has used resulting in PT entries being leaked. This is shown
by running xe_vm.bind-array-conflict-error-inject on a VRAM device going
into a suspend state after the test completes.

v2:
 - s/childern/children (CI, Matt Auld)
