[PATCH v1] net/ice/base: fix switch rules not cleared on warm reset

[PATCH v1] net/ice/base: fix switch rules not cleared on warm reset

[Steve Yang]

When users killed app forcely (e.g.: kill -9 pid), the driver reset
couldn't make all registers of NIC recovery to initial status.
For example, the switch filter rules, which involved the vlan tag,
couldn't be added.

Tell the Firmware to shut down the AdminQ to avoid possible error
when process was killed abnormally.
