nfs: fix RCU cl_xprt handling in nfs_swap_activate/deactivate
sparse says:
fs/nfs/file.c:543:60: warning: incorrect type in argument 1 (different address spaces)
fs/nfs/file.c:543:60: expected struct rpc_xprt *xprt
fs/nfs/file.c:543:60: got struct rpc_xprt [noderef] <asn:4>*cl_xprt

fs/nfs/file.c:548:53: got struct rpc_xprt [noderef] <asn:4>*cl_xprt
cl_xprt is RCU-managed, so we need to take care to dereference and use
it while holding the RCU read lock.
