Juergen Gross 58faf07b76 xen: make use of xenbus_read_unsigned() in xen-pcifront ...

Use xenbus_read_unsigned() instead of xenbus_scanf() when possible.
This requires to change the type of the read from int to unsigned,
but this case has been wrong before: negative values are not allowed
for the modified case.
