[IA64] Fix possible invalid memory access in ia64_setup_msi_irq()
The following 'if' statement in ia64_setup_msi_irq() always fails even
if create_irq() returns <0 value, because variable 'irq' is defined as
unsigned int. It would cause invalid memory access.
irq = create_irq();
if (irq < 0)
return irq;
