xen: stringify assertion condition for printing sooner.

So that:
(XEN) Assertion '!(((*({ unsigned long __ptr; __asm__ ("" :
"=r"(__ptr) : "0"(&per_cpu____preempt_count));
(typeof(&per_cpu____preempt_count)) (__ptr +
(get_cpu_info()->per_cpu_offset)); }))) ||
((irq_stat[(((get_cpu_info()->processor_id)1...
becomes:
(XEN) Assertion '"!in_atomic()"' failed at softirq.c:61
