NFS: Remove unused variable "pages_ptr"

This variable is initialized to NULL and is never modified before being
passed to nfs_readdir_free_large_page(). But that's okay, because
nfs_readdir_free_large_page() only seems to exist as a way of calling
nfs_readdir_free_pagearray() without this parameter. Let's simplify by
removing pages_ptr and nfs_readdir_free_pagearray().
