[CI 1/2] drm/xe: Use a helper to get delta run ticks from the exec queue

[Umesh Nerlige Ramappa <umesh.nerlige.ramappa@intel.com>]

As per earlier review feedback - code manipulating exec queue fields
should not be present in xe_device.c. Use a helper to get the delta run
ticks from exec queue.

v2: Drop the Fixes tag
