Subject: PCI/MSI: Return failure when msix_setup_entries() fails

From: Christophe JAILLET <[email protected]>

[ 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.
