[Qemu-devel] [PATCH 10/12] chardev: honour the reconnect setting in tcp_chr_wait_connected

["Daniel P. Berrangé" <berrange@redhat.com>]

If establishing a client connection fails, the tcp_chr_wait_connected
method should sleep for the reconnect timeout and then retry the
attempt. This ensures the callers don't immediately abort with an
error when the initial connection fails.
