[Intel-wired-lan] [PATCH iwl-net v10 3/5] Revert "iavf: Do not restart Tx queues after reset task failure"

[Mateusz Palczewski <mateusz.palczewski@intel.com>]

From: Marcin Szycik <marcin.szycik@linux.intel.com>

This reverts commit 08f1c147b7265245d67321585c68a27e990e0c4b.

Netdev is no longer being detached during reset, so this fix can be
reverted. We leave the removal of "hacky" IFF_UP flag update.
