drm/i915: Fix i915_dma_map_single positive error code

i915_dma_map_single relies on dma_mapping_error, which returns positive
error codes. Found by static checker.

Introduced by commit 678d96fbb3b5995a2fdff2bca5e1ab4a40b7e968
("drm/i915: Track GEN6 page table usage").

v2: Return negative error code and renamed commit title. (Dan)
v3: Missing reported-by tag (Daniel)
