[Mellanox] Handle exception during Inotify import (#21469)

- Why I did it
During smartswitch initialization, an error is observed during switch bootup. ztp disable runs decode-eeprom.
Happens during ztp because, ztp sets DEBUG="" here https://github.com/sonic-net/sonic-ztp/blob/202411/src/etc/default/ztp#L6

- How I did it
Fixed the import in inotify

- How to verify it
Verified by running decode-eeprom during init
