genirq/msi: Take the per-device MSI lock before validating the control structure
Calling msi_ctrl_valid() ultimately results in calling
msi_get_device_domain(), which requires holding the device MSI lock.
However, in msi_domain_populate_irqs() the lock is taken right after having
called msi_ctrl_valid(), which is just a tad too late.
Take the lock before invoking msi_ctrl_valid().
