net: hns3: fixed vf get max channels bug

IronShen · Paolo Abeni · commit b3e75c0bcc53 · 2025-07-24T11:27:21.000+02:00
Currently, the queried maximum of vf channels is the maximum of channels supported by each TC. However, the actual maximum of channels is the maximum of channels supported by the device.
