Cai Xinchen 53915ecc43 rapidio: devices: fix missing put_device in mport_cdev_open 
[ Upstream commit d5b6e6eba3af11cb2a2791fa36a2524990fcde1a ]

When kfifo_alloc fails, the refcount of chdev->dev is left incremental.
We should use put_device(&chdev->dev) to decrease the ref count of
chdev->dev to avoid refcount leak.
