rG9930150214d1: ufshci: skip the reinit when the new link works
Summary

UFSHCI_QUIRK_REINIT_AFTER_MAX_GEAR_SWITCH always rebuilt the
link after the gear switch. It threw away a working HS link and
ended up in PWM. The reinit is only needed for a dead link.
There the local side reports HS and the peer never answers. A
local readback cannot tell the two apart. Peer traffic can.

Probe the peer with DME_PEER_GET after the switch. Skip the
reinit when the probe succeeds. Log it when the probe fails.
