net/af_packet: register supported param fanout mode

Although af_packet PMD supports setting the fanout algorithm, it is not
explicitly declared during registration. Add fanout parameter registration
to facilitate users in quickly obtaining supported fanout algorithms.

Additionally, add configuration parameter printing during initialization.

Adjust unnecessary printing to debug level.
