[patch] xm: Add missing AUTO_PHP_SLOT

[Simon Horman]

This patch changes over a few sections of code that
I missed when adding AUTO_PHP_SLOT to signify that
qemu-xen should pick a slot - previously 0 was used.

I have not experienced any breakage as a result of these
changes being missing, nor am I even sure that is possible.
But it seems worthwhile to clean things up in this way for 3.4.
And possibly remove the (spurious?) checks afterwards.
