Oleksij Rempel 24023ed8ff net: selftests: initialize TCP header and skb payload with zero ...

commit 9e8d1013b0c38910cbc9e60de74dbe883878469d upstream.

Zero-initialize TCP header via memset() to avoid garbage values that
may affect checksum or behavior during test transmission.

Also zero-fill allocated payload and padding regions using memset()
after skb_put(), ensuring deterministic content for all outgoing
test packets.
