[PATCH 2/4] pch_gbe: fix transmit watchdog timeout

Author: Andy Cress [off-list ref]

An extended ping and iperf test with 6 vlans resulted in transmit
timeout stats 
and sometimes a driver oops with a netdev watchdog transmit timeout.
Fix WATCHDOG_TIMEOUT to be more like e1000e at 5 * HZ, to avoid 
unnecessary transmit timeouts.
