If current qbuf entry is already present in release buffer list, then as part of release done, refcount will get decremented and for current qbuf, there is 2 possibilities of outputs from fw. FBD with RO and wo RO. So if firmware gives FBD with RO, we are currently decrementing refcount from 1 -> 0. So mapping gets destroyed. But firmware is still holding RO referrence and leading to smmu fault issues. So added hadling to increment recount by 1, if current buffer(qbuf) is already present in release buf list.
