cifs: use locks_inode_context helper
cifs currently doesn't access i_flctx safely. This requires a smp_load_acquire, as the pointer is set via cmpxchg (a release operation). Cc: Steve French <smfrench@samba.org> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jeff Layton <jlayton@kernel.org>
