This reverts commit 7255355a0636b4eff08d5e8139c77d98f151c4fc.
After this commit we are not able to attach VF to VM:
virsh attach-interface v0 hostdev --managed 0000:41:01.0 --mac 52:52:52:52:52:52
error: Failed to attach interface
error: Cannot set interface MAC to 52:52:52:52:52:52 for ifname enp65s0f0np0 vf 0: Resource temporarily unavailable
ice_check_vf_ready_for_cfg() already contain waiting for reset.
New condition in ice_check_vf_ready_for_reset() causing only problems.
Fixes: 7255355a0636 ("ice: Fix ice VF reset during iavf initialization")
