igb: remove redundant timer updates and cleanup watchdog_task
The igb watchdog task is modifying the watchdog timer twice duing a single
run. It only needs to be called once to reschedule itself for 2 seconds from
the last time it ran.
In addition I removed the allocation of the mac_info structure since it is
only called twice and is easier to access via the e1000_hw struct.
