xen/spinlock: Fix check from greater than to be also be greater or equal to.

During review of git commit cb9c6f15f318aa3aeb62fe525aa5c6dcf6eee159
("xen/spinlock:  Check against default value of -1 for IRQ line.")
Stefano pointed out a bug in the patch. Unfortunatly due to vacation
timing the fix was not applied and this patch fixes it up.
