rxrpc: Fix error handling in rxgk_extract_token()

Fix a missing bit of error handling in rxgk_extract_token(): in the event
that rxgk_decrypt_skb() returns -ENOMEM, it should just return that rather
than continuing on (for anything else, it generates an abort).

Fixes: 64863f4ca494 ("rxrpc: Fix unhandled errors in rxgk_verify_packet_integrity()")
