pci: Convert msi_init() to Error and fix callers to check it
msi_init() reports errors with error_report(), which is wrong
when it's used in realize().
Fix by converting it to Error.
Fix its callers to handle failure instead of ignoring it.
For those callers who don't handle the failure, it might happen:
when user want msi on, but he doesn't get what he want because of
msi_init fails silently.
