[PATCH] drm/xe/tlb: Init range tilemask err to zero

[Jonathan Cavitt <jonathan.cavitt@intel.com>]

Initialize err = 0 in xe_tlb_inval_range_tilemask_submit to prevent a
possible uninitialized value return in the case where the tile_mask
somehow doesn't match any available tile ids.

This targets a static analysis issue.
