i40e: Fix VFs not created
[ Upstream commit dc8812626440fa6a27f1f3f654f6dc435e042e42 ]
When creating VFs they were sometimes not getting resources.
It was caused by not executing i40e_reset_all_vfs due to
flag __I40E_VF_DISABLE being set on PF. Because of this
IAVF was never able to finish setup sequence never
getting reset indication from PF.
Changed test_and_set_bit __I40E_VF_DISABLE in
i40e_sync_filters_subtask to test_bit and removed clear_bit.
This function should not set this bit it should only check
if it hasn't been already set.
Fixes: a7542b876075 ("i40e: check __I40E_VF_DISABLE bit in i40e_sync_filters_subtask")
