[HW, TOOLS] Improve VSTAT output in case of a driver startup failure. [MLNX: 2819]

When low level drivers fail on startup, which usually happens upon an incorrect FW, they report to all the above stack a dev_id of the burning device ("livefish") and imitate such a device thereafter. It was done in order to allow to all the upper level drivers to start their work.
VSTAT shows in this case the dev_id of a "livefish", which is a bit misleading.

This patch fixes this behavior. VSTAT will now show the real dev_id. The drivers  still imitate the "livefish" device. The detailed message about the startup failure can be found in System Event Log (as it always was).
