drm/msm: Adjust msm_iommu_pagetable_prealloc_allocate() allocation type

Browse Source 
In preparation for making the kmalloc family of allocators type aware,
we need to make sure that the returned type from the allocation matches
the type of the variable being assigned. (Before, the allocator would
always return "void *", which can be implicitly cast to any pointer type.)

The assigned type is "void **" but the returned type will be "void ***".
These are the same allocation size (pointer size), but the types do not
match. Adjust the allocation type to match the assignment.
