This driver was indexing the contexts by asid-1, which is probably
done under the assumption that the first ASID is always 1.

Unfortunately this is not entirely true: at least in the MSM8956
and MSM8976 GPU IOMMU, the gpu_user context's ASID number is zero.
To allow using an asid number of zero, stop indexing the contexts
by asid-1 and rather index them by asid.

msm8974 will need this as well.
