[PATCH mptcp-next v6 3/4] selftest: mptcp: exit from copyfd_io_poll() when receive SIGUSR1

[menglong8.dong@gmail.com]

From: Menglong Dong <imagedong@tencent.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.
