OPTIM: ebtree: make ebmb_insert_prefix() keep a copy the new node's pfx looking at a perf profile while loading a conf with a huge map, it appeared that there was a hot spot on the access to the new node's prefix, which is unexpectedly being reloaded for each visited node during the tree descent. Better keep a copy of it because with large trees that don't fit into the L3 cache the memory bandwidth is scarce. Doing so reduces the load time from 8.0 to 7.5 seconds.
