msm: camera: memmgr: Set name for dma buffer to help profiling

For dma buffer profiling,we don't konw the owner of one dma
buffer. So we add it's name to show it's owner.
If you use v1 struct to alloc/map dma buffer it will use
default buffer name "UNKNOWN". For v2 struct you can set dma
buffer name at UMD side.
