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.
