i40e: hush little warnings

BugLink: http://bugs.launchpad.net/bugs/1536474

These messages seem big and scary, but they're really not. The driver
can fully recover from any of these. The overflow error in particular
can happen when enabling a bunch of VFs and the VF driver is not
blacklisted.

Since these messages are really for debugging purposes, reclassify
them as such.
