PCI/MSI: Return failure when msix_setup_entries() fails
[ Upstream commit 3adfb572f2978a980b250a9e1a56f84f3a031001 ]
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: e75eafb9b039 ("genirq/msi: Switch to new irq spreading infrastructure")
