dnsdist: Fix unlimited retries when TCP Fast Open is enabled

Using the same flag to indicate whether a connection was reused
after being pulled from the pool AND to know if the TFO flag should
be passed to sendmsg() led to an unlimited number of reconnection
attemps when TFO was enabled and the backend closed the connection
right after a write (sendmsg() succeeds then read() returns 0 right
away).
