There are multiple instances of code reading an optional unsigned
parameter from Xenstore via xenbus_scanf(). Instead of repeating the
same code over and over add a service function doing the job and
replace the call of xenbus_scanf() with the call of the new function
where appropriate.

As this seems to be a series that will go through some tree other
than mine, I assume the networking bits will be taken care of that
way.
