iommu: msm: Don't treat address 0 as an error case
Currently, the iommu page table code treats a scattergather
list with physical address 0 as an error. This may not be
correct in all cases. Physical address 0 is a valid part
of the system and may be used for valid page allocations.
Nothing else in the system checks for physical address 0
for error so don't treat it as an error.
