Subject: [PATCH] Fix: libcrmcommon: avoid file descriptor leak in IPC client
 with async connection

Previously if qb_ipcc_connect_async() succeeded but the following poll()
failed, the file descriptor would leak.

In that case, given that disconnect function is not registered yet,
qb_ipcc_disconnect() won't clean up the socket. In any case, call
qb_ipcc_connect_continue() here so that it may fail and do the cleanup
for us.

Issue introduced in 2.1.3 by 4b60aa100.
