NFSv4: Don't use the delegation->inode in nfs_mark_return_delegation()
commit ed1e6211a0a134ff23592c6f057af982ad5dab52 upstream.
nfs_mark_return_delegation() is usually called without any locking, and
so it is not safe to dereference delegation->inode. Since the inode is
only used to discover the nfs_client anyway, it makes more sense to
have the callers pass a valid pointer to the nfs_server as a parameter.
