[PATCH iwl-net 0/5] iavf: five correctness fixes

[Aleksandr Loktionov <aleksandr.loktionov@intel.com>]

Small batch of iavf bug fixes.  Patches address a NULL-pointer dereference
crash in the hung-tx detector, a spurious free_irq() call in the misc-IRQ
error path, a VSI-state-corruption race when ethtool changes ring parameters
during an active reset, an inverted TC-boundary comparison that silently
steered frames to non-existing traffic classes, and an -EINVAL that confused
upper layers when a TC flower filter was looked up after its qdisc had
already been torn down.

All five are genuine correctness fixes with no functional changes for the
common path.  Best routed via net.
