nvethernet: clear tx_usecs_timer_armed atomic variable

Browse Source 
Issue: If the interface goes down by setting tx_usecs_timer_armed
to OSI_ENABLE then after interface is up Tx timer will not be fired
because tx_usecs_timer_armed is set to OSI_ENABLE.

Fix: Clear tx_usecs_timer_armed when interface going down.
