net/bonding: use evenly distributed default RSS RETA

Default Redirection Table that is set in bonding driver is distributed
evenly over all Rx queues only within every RETA group (the first RETA
entries in every group are always start with zero). But in the most
drivers, default RETA is distributed over all Rx queues without sequence
resets in the beginning of a new group, which implies more balanced
per-core load.

Change the default RETA to be evenly distributed over all Rx queues
considering the whole table.
