Improve mxge watchdog routine's ability to reliably reset a failed NIC:

- Mark the link as down, so if watchdog reset fails, link watching
    failover software can notice it
- Don't send MXGEFW_CMD_ETHERNET_DOWN if the NIC has been reset, it is
    not needed, and will fail on a freshly reset NIC.
- Ensure the transmit routines aren't attempting to PIO write to doorbells
    while the NIC is being reset.
- Download the correct f/w, rather than using the EEPROM f/w after reset.
- Export a count of the number of watchdog resets via sysctl
- Zero all f/w stats at reset.  This will lead to less confusing
    diagnostic output when investigating NIC failures.
