iflib: Set the get counter routine prior to attaching the interface

Browse source 
This ensures other threads, e.g. ioctl threads, see the correct counter
routine once after the interface has been attached.

This change partially reverts commit 23ac9029f9, which for unclear
reason moved setting the get counter routine after ether_ifattach().
