Subject: transfer: abort pause send when connection is marked for closing
X-Git-Tag: curl-8_5_0~25

transfer: abort pause send when connection is marked for closing

This handles cases of some bi-directional "upgrade" scenarios
(i.e. WebSockets) where sending is paused until some "upgrade" handshake
is completed, but server rejects the handshake and closes the
connection.

Closes #12428
