[PATCH net-next 11/12] mlxsw: Remove resource query check

Ido Schimmel
2022-02-22T17:18:48Z

Since SwitchX-2 support was removed in commit b0d80c013b04 ("mlxsw:
Remove Mellanox SwitchX-2 ASIC support"), all the ASICs supported by
mlxsw support the resource query command.

Therefore, remove the resource query check and always query resources
from the device.
