net/ena: skip timer if reset is triggered

[ upstream commit e2174a54469febb2905f06d5c942ff76c492c2ff ]

Some user applications may not support PMD reset handling. If they will
support timer service it could cause a situation, when information
about the reset trigger is being showed every time the timer service is
being called.

Timer service is now being skipped if the reset was already triggered.
