usbnet: mcs7830: rework link state detection
Even with the quirks in commit dabdaf0c (mcs7830: Fix link state detection) there are still spurious link-down events for some chips where the false link-down events count go over a few hundreds. This patch takes a more conservative approach and only looks at link-down events where the link-down state is not combined with other states (e.g. half/full speed, pending frames in SRAM or TX status information valid). In all other cases we assume the link is up. Tested on MCS7830CV-DA (USB ID 9710:7830).
