The two functions ifnet_byindex() and ifnet_byindex_locked() are exactly the
same after the network stack was epochified. Merge the two into one function
and cleanup all uses of ifnet_byindex_locked().

While at it:
- Add branch prediction macros.
- Make sure the ifnet pointer is only deferred once,
  also when code optimisation is disabled.
