Jian Shen 472a2ff63e net: hns3: fix add VLAN fail issue 
The hclge_sync_vlan_filter is called in periodic task,
trying to remove VLAN from vlan_del_fail_bmap. It can
be concurrence with VLAN adding operation from user.
So once user failed to delete a VLAN id, and add it
again soon, it may be removed by the periodic task,
which may cause the software configuration being
inconsistent with hardware. So add mutex handling
to avoid this.
