Two more mxge watchdog fixes:

1) Restore the PCI Express control register after a watchdog
   reset.  This is required because the device will come out
   of watchdog reset with the pectl reg at its default state,
   and important BIOS configuration (like max payload size)
   could be lost.

2) Call mxge_start_locked() for every tx queue before dropping
   the lock in the watchdog handler.   This is required, as
   the queue's buf ring may have filled during the reset.
