[PATCH 6.18 112/275] rxrpc: Fix error handling in rxgk_extract_token()

[Greg Kroah-Hartman]

6.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: David Howells <dhowells at redhat.com>

commit 3476c8bb960f48e49355d6f93fb7673211e0163f upstream.

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()")
