[PATCH] nvme-pci: remove redundant dma frees in hmb

[francis.p at samsung.com]

From: Francis Pravin <francis.p at samsung.com>

The value of size is 0 when there is no dma buffer allocated. The value
of i also remains 0. So, no need to free the dma buffer in out_free_bufs.
Hence, remove the redundant dma frees.
