Dawid Wesierski 7255355a06 ice: Fix ice VF reset during iavf initialization 
Fix the current implementation that causes ice_trigger_vf_reset()
to start resetting the VF even when the VF-NIC is still initializing.

When we reset NIC with ice driver it can interfere with
iavf-vf initialization e.g. during consecutive resets induced by ice

iavf                ice
  |                  |
  |<-----------------|
  |            ice resets vf
 iavf                |
 reset               |
 start               |
  |<-----------------|
  |             ice resets vf
  |             causing iavf
  |             initialization
  |             error
  |                  |
 iavf
 reset
 end

This leads to a series of -53 errors
(failed to init adminq) from the IAVF.

Change the state of the vf_state field to be not active when the IAVF
is still initializing. Make sure to wait until receiving the message on
the message box to ensure that the vf is ready and initializded.

In simple terms we use the ACTIVE flag to make sure that the ice
driver knows if the iavf is ready for another reset

  iavf                  ice
    |                    |
    |                    |
    |<------------- ice resets vf
  iavf           vf_state != ACTIVE
  reset                  |
  start                  |
    |                    |
    |                    |
  iavf                   |
  reset-------> vf_state == ACTIVE
  end              ice resets vf
    |                    |
    |                    |
