From: Jian Shen <shenjian15@huawei.com>
Currently, when host set VF untrusted, the driver will disable
the promisc mode of VF. It may be conflicted when the VF requests
the host to set promisc mode. So refactor it by changing promisc
mode for VF asynchronously. With this change, the promisc mode of
VF can be restored when the VF being trusted again.

Currently, PF is using HCLGE_STATE_PROMISC_CHANGED to indicate
need synchronize the promisc mode for itself, and using flag
HCLGE_VPORT_STATE_PROMISC_CHANGE for its VF. To keep consistent,
remove flag HCLGE_STATE_PROMISC_CHANGED, and use flag
HCLGE_VPORT_STATE_PROMISC_CHANGE instead.
