[ Upstream commit 2f61353cd2f789a4229b6f5c1c24a40a613357bb ]
Since some interrupt states may be cleared by hardware, the driver
may receive an empty interrupt. Currently, the VF driver directly
disables the vector0 interrupt in this case. As a result, the VF
is unavailable. Therefore, the vector0 interrupt should be enabled
in this case.
Fixes: b90fcc5bd904 ("net: hns3: add reset handling for VF when doing Core/Global/IMP reset")
