fixes a memory leak that occurs when a readdir loop doesn't complete, since the cookie was only freed on the last readdir upcall. by storing the cookie with nfs41_open_state, we can avoid passing the cookie to the driver and back, and not worry about having to free it separately

in handle_mount(), the call to nfs41_lookup() requires a mutable nfs41_abs_path because it can change on referrals, so make a copy for it
removed unused fields in struct nfs41_root and related arguments to nfs41_root_create()

because we no longer have to convert strings from unicode, we can avoid copying them out of the upcall buffer
