NFSv4.1: Optimise layout return-on-close Optimise the layout return on close code by ensuring that 1) Add a check for whether we hold a layout before taking any spinlocks 2) Only take the spin lock once 3) Use nfs_state->state to speed up open file checks Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
