[PATCH net 3/3] rxrpc: Fix error handling in rxgk_extract_token()

[David Howells]

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()")
Closes: https://sashiko.dev/#/patchset/20260422161438.2593376-4-dhowells@xxxxxxxxxx
