Wen Yang 098336deb9 drm/msm: Fix error return checking ...

The error checks on ret for a negative error return always fails because
the return value of iommu_map_sg() is unsigned and can never be negative.

Detected with Coccinelle:
drivers/gpu/drm/msm/msm_iommu.c:69:9-12: WARNING: Unsigned expression
compared with zero: ret < 0
