In order to support Xenstore-stubdom live update, the 9pfs device used

obviously not possible before having read the saved state).
Add an alternative init function for a 9pfs device supporting to take
the configuration from the kexec module instead of Xenstore. Add
support for creating the device using the kexec module, too.
