[dpdk-dev] [PATCH v3 2/2] net/failsafe: fix duplicate event registration

When the fail-safe device is reconfigured, it attempts to register
again for the sub-devices LSC and RMV events.
Prevent an event registration if it is already done.
Fixes: 598fb8aec6f6 ("net/failsafe: support device removal")
