msm: camera: memmgr: suppress set mapped dmabuf name failed log

we can't set dma buffer name when it has been attached to hardware.
As usually UMD allocate one buffer then map it at KMD side. So most of time,
set mapped dma buffer name failed. But it's not a fault error. So
we move log to debug level.
