Indentation is off.

Otherwise, the interface looks clean. I can't tell from this patch
whether the file is opened by qemu_open() (probably in
net_dump_state_init() in an earlier patch of the series); but if not,
you should fix that.  That way, I can pass '/dev/fdset/XXX' as the name
for an fd passed in by an earlier 'add-fd' even if qemu is restricted
from open()ing files directly.
