When a bad checksum is detected and a single subflow is in use, don't
send RST + MP_FAIL, send data_ack + MP_FAIL instead.

So invoke tcp_send_active_reset() only when mptcp_has_another_subflow()
is true.

Hi Greg -

Please drop this patch from the 5.18-stable queue. It was the first of an 8-patch series and doesn't really stand alone.

This commit message lacks the Fixes: tag and the magic commit message words that I've seen the scripts pick up, so I'm curious: was this patch selected by hand?

Yup, between the commit message and the code itself, it looked like a
fix for AUTOSEL.
