[PATCH] drm/xe: Drop unnecessary GT lookup in xe_exec_queue_create_ioctl()

[Matt Roper]

xe_exec_queue_create_ioctl() performs a lookup of the xe_gt for the GT
ID passed from userspace, but the result is never actually used.  Since
there's already a separate (and earlier) check that the ID passed from
userspace is valid, the unnecessary lookup can be removed.
