drm/xe: Fix an IS_ERR() vs NULL bug in xe_tile_alloc_vram()

Browse Source 
commit 6c9e64e83b upstream.

The xe_vram_region_alloc() function returns NULL on error.  It never
returns error pointers.  Update the error checking to match.

Fixes: 4b0a5f5ce7 ("drm/xe: Unify the initialization of VRAM regions")
