msm: ultrasound: ignore kmemleak false detection 



The kmemleak tool detects a false memory leak, beacuse a
memory allocation result is assigned to a non-aligned
pointer. When kmemleak scans the memory for references
to this allocated block, it does not find any.

The fix adds a kmemleak call to explicity ignore this
allocation.
