net: Do not clear the sock TX queue in sk_set_socket()
[ Upstream commit 41b14fb8724d5a4b382a63cb4a1a61880347ccb8 ]
Clearing the sock TX queue in sk_set_socket() might cause unexpected
out-of-order transmit when called from sock_orphan(), as outstanding
packets can pick a different TX queue and bypass the ones already queued.
This is undesired in general. More specifically, it breaks the in-order
scheduling property guarantee for device-offloaded TLS sockets.
Remove the call to sk_tx_queue_clear() in sk_set_socket(), and add it
explicitly only where needed.
Fixes: e022f0b4a03f ("net: Introduce sk_tx_queue_mapping")
