ceph: set pool_ns in new inode layout for async creates
commit4584a768f2
upstream. Dan reported that he was unable to write to files that had been asynchronously created when the client's OSD caps are restricted to a particular namespace. The issue is that the layout for the new inode is only partially being filled. Ensure that we populate the pool_ns_data and pool_ns_len in the iinfo before calling ceph_fill_inode.
