Subject: [PATCH] drm/xe: fix WQ_MEM_RECLAIM passed as max_active to alloc_workqueue()

Workqueue xe-ggtt-wq has been allocated using WQ_MEM_RECLAIM, but
the flag has been passed as 3rd parameter (max_active) instead
of 2nd (flags) creating the workqueue as per-cpu with max_active = 8
(the WQ_MEM_RECLAIM value).

So change this by set WQ_MEM_RECLAIM as the 2nd parameter with a
default max_active.
