rxgk: Fix potential integer overflow in length check
Fix potential integer overflow in rxgk_extract_token() when checking the
length of the ticket. Rather than rounding up the value to be tested
(which might overflow), round down the size of the available data.
Fixes: 2429a1976481 ("rxrpc: Fix untrusted unsigned subtract")
