NFSv4: Don't modify the change attribute cached in the inode
When the client is caching data and a write delegation is held, then the server may send a CB_GETATTR to query the attributes. When this happens, the client is supposed to bump the change attribute value that it returns if it holds cached data. However that process uses a value that is stored in the delegation. We do not want to bump the change attribute held in the inode. Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>
