PCI/MSI: Return failure when msix_setup_entries() fails

Browse source 
If alloc_msi_entry() fails, we free resources and set ret = -ENOMEM.

However, msix_setup_entries() returns 0 unconditionally.  Return the error
code instead.

Fixes: e75eafb9b0 ("genirq/msi: Switch to new irq spreading infrastructure")
