genirq/msi: Check for the presence of an irq domain when validating msi_ctrl
For architectures such as s390 and powerpc that do not use
irq domains for MSIs, dev->msi.domain is always NULL, so
the per-device, per-bus MSI domain is also guaranteed to
be NULL.
So checking one without checking the other is bound to result
in a splat, followed by a memory leak as we don't free the MSI
descriptors.
Add the missing check.
