Robert Watson 6852110b64 Rather than using IFNET_RLOCK() when iterating over (and modifying) the ...

ifnet list during if_ef load, directly acquire the ifnet_sxlock
exclusively.  That way when if_alloc() recurses the lock, it's a write
recursion rather than a read->write recursion.

This code structure is arguably a bug, so add a comment indicating that
this is the case.  Post-8.0, we should fix this, but this commit
resolves panic-on-load for if_ef.
