A couple of fixes for iavf's reset issues that can happen in the early
states (before configuring IRQs, queues, ..etc).

Ahmed Zaki (2):
  iavf: fix reset in early states
  iavf: allow an early reset event to be processed

Stress testing is showing errors like:

[ 3193.412996] iavf 0000:b1:01.0: Unable to get VF config (-5)
[ 3197.115178] iavf 0000:b1:01.0: Admin queue command never completed

and

[ 3274.183144] iavf 0000:b1:01.0: Failed to init Admin Queue (-53)


more than we usually see. I will send a new version that better handles 
these errors paths.

@tony, please drop from iwl next-queue for now.
