Do not set timers after the connection is closed.
The qc->closing flag is set when a connection close is initiated for the first
time.
No timers will be set if the flag is active.
TODO: this is a temporary solution to avoid running timer handlers after
connection (and it's pool) was destroyed. It looks like currently we have
no clear policy of connection closing in regard to timers.
