Subject: [PATCH net-next 8/9] selftest: mptcp: exit from copyfd_io_poll() when receive SIGUSR1

From: Menglong Dong <imagedong@...cent.com>

For now, mptcp_connect won't exit after receiving the 'SIGUSR1' signal
if '-r' is set. Fix this by skipping poll and sleep in copyfd_io_poll()
if 'quit' is set.
