tty: Fix SIGTTOU not sent with tcflush()
commit 5cec7bf699c61d14f0538345076480bb8c8ebfbb upstream.
Commit 'e7f3880cd9b98c5bf9391ae7acdec82b75403776'
tty: Fix recursive deadlock in tty_perform_flush()
introduced a regression where tcflush() does not generate
SIGTTOU for background process groups.
Make sure ioctl(TCFLSH) calls tty_check_change() when
invoked from the line discipline.
