Yash Upadhyay 96ff7cbcd8 msm: camera: sync: Avoiding UAF on get dma fence ...

Two threads can access same dma fence, one to get_fence and other
to put_fence. Missing locks and checks on fence could lead to use
after free case. This change adds proper locks and checks before
dma fence get call to avoid this.
