firewire: nosy: char device is not seekable
Amend .open handler accordingly and remove the .llseek handler.
.llseek = NULL means no_llseek (return error) since commit 776c163b1b93.
The only client that uses this interface is nosy-dump in linux/tools/firewire
and it knows not to seek in this char dev.
