CVE-2024-44995

In the Linux kernel, the following vulnerability has been resolved:

net: hns3: fix a deadlock problem when config TC during resetting

When config TC during the reset process, may cause a deadlock, the flow is as below: pf reset start │ ▼ ...... setup tc │ │ ▼ ▼ DOWN: napidisable() napidisable()(skip) │ │ │ ▼ ▼ ...... ...... │ │ ▼ │ napienable() │ ▼ UINIT: netifnapidel() │ ▼ ...... │ ▼ INIT: netifnapiadd() │ ▼ ...... global reset start │ │ ▼ ▼ UP: napienable()(skip) ...... │ │ ▼ ▼ ...... napi_disable()

In reset process, the driver will DOWN the port and then UINIT, in this case, the setup tc process will UP the port before UINIT, so cause the problem. Adds a DOWN process in UINIT to fix it.
