irqchip/irq-msi-lib: Check for NULL ops in msi_lib_irq_domain_select()
The irq_domain passed to msi_lib_irq_domain_select() may not have
msi_parent_ops set. There is a NULL pointer check for it, but unfortunately
there is a dereference of the parent ops pointer before that.
Move the NULL pointer test before the first use of that pointer.
This was found on a MacchiatoBin (Marvell Armada 8K SoC), which uses the
irq-mvebu-sei driver.
