migration: Fix fd protocol for incoming defer Currently, incoming migration through fd supports only command-line case: E.g. fork(); fd = open(); exec("qemu ... -incoming fd:%d", fd); It's possible to use add-fd commands to pass fd for migration, but it's invalid case. add-fd works with fdset but not with particular fds. To work with getfd in incoming defer it's enough to use monitor_fd_param instead of strtol. monitor_fd_param supports both cases: * fd:123 * fd:fd_name (added by getfd). And also the use of monitor_fd_param improves error messages.
