Merge branch 'qed-IOV-cleanups'

Yuval Mintz says:

====================
qed: IOV related clenaups

This patch series targets IOV functionality [on both PF and VF].

Patches #2, #3 and #5 fix flows relating to malicious VFs, either by
upgrading and aligning current safe-guards or by correcing racy flows.

Patches #1 and #8 make some malicious/dysnfunctional VFs logging appear
by default in logs.

The rest of the patches either cleanup the existing code or else correct
some possible [yet fairly insignicant] issues in VF behavior.
