net/9p: Switch to wait_event_killable()
commit 9523feac272ccad2ad8186ba4fcc89103754de52 upstream.
Because userspace gets Very Unhappy when calls like stat() and execve()
return -EINTR on 9p filesystem mounts. For instance, when bash is
looking in PATH for things to execute and some SIGCHLD interrupts
stat(), bash can throw a spurious 'command not found' since it doesn't
retry the stat().
In practice, hitting the problem is rare and needs a really
slow/bogged down 9p server.
