fix(ct): correctly pass reverse key for deletion from conntrack map

[SRodi]

Description

We wrongly pass key reference to _ct_should_report_packet when the connection is found based on the reverse_key, this key is then removed as part of GC when the connection timed out or if it is a TCP connection and FIN or RST flags are set.

This PR fixes the issue by passing the correct key reference which is reverse_key
