fanotify: sanitize failure exits in copy_event_to_user()
* do copy_to_user() before prepare_for_access_response(); that kills the need in remove_access_response(). * don't do fd_install() until we are past the last possible failure exit. Don't use sys_close() on cleanup side - just put_unused_fd() and fput(). Less racy that way... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
