PCI: aardvark: Fix return value of MSI domain .alloc() method
MSI domain callback .alloc() (implemented by advk_msi_irq_domain_alloc() function) should return zero on success, since non-zero value indicates failure. When the driver was converted to generic MSI API in commit f21a8b1b6837 ("PCI: aardvark: Move to MSI handling using generic MSI support"), it was converted so that it returns hwirq number. Fix this.
