afs: Make struct afs_read::remain 64-bit
Make struct afs_read::remain 64-bit so that it can handle huge transfers if we ever request them or the server decides to give us a bit extra data (the other fields there are already 64-bit). Signed-off-by: David Howells <dhowells@redhat.com> Tested-by: Marc Dionne <marc.dionne@auristor.com>
