I'm agnostic on the change... As long as we get a message somewhere
when the failure is meaningful, I'm fine with this change. I didn't
like setting mwi by the driver anyway - it should have already been
done by the platform.

Why remove the warning? Presumably people want to know if pci_set_mwi
failed.
Randy, this was your change, right?
Uh, I think that my thinking was like this:
pci_try_set_mwi() and pci_set_mwi() are both "try best effort"
functions. Neither of them guarantees that pci_set_cacheline_size()
will succeed. And in case of serious problems, pci_set_cacheline_size()
will print a (KERN_DEBUG) message.
Anyway, I don't mind restoring the former lpfc code if that is what
should be done.
