net/failsafe: advertise supported RSS functions

Advertise failsafe supported RSS functions as part of dev_infos_get
callback. Set failsafe default RSS hash functions to be:
ETH_RSS_IP, ETH_RSS_UDP, and ETH_RSS_TCP.
The result of failsafe RSS hash functions is the logical AND of the
RSS hash functions among all failsafe sub_devices and failsafe own
defaults.

Previous to this commit RSS support was reported as none. Since the
introduction of [1] it is required that all RSS configurations be
verified.
