Fix an issue when firmware logging stops after devlink reload action
driver_reinit or driver reset. After the driver reinits and resumes
operations, it must re-request event notifications from the firmware
as a part of its recofiguration.
Fix it by restoring fw logging when it was previously registered
before these events.

Restoring fw logging in these cases was faultily removed with new
debugfs fw logging implementation.

Failure to init fw logging is not a critical error so it is safely
ignored. Information log in case of failure are handled by
ice_fwlog_register function.
