MFC 206429:
Sync em(4) and igb(4) drivers with 8 except for VF support:
- Remove unneeded rxtx handler, make que handler generic in igb.
- Do not allocate header mbufs in rx ring if not doing hdr split in igb.
- Release the lock in rxeof call to stack.
- Change rxeof api for poll friendliness, and eliminate unnecessary link
  tasklet use.
- Move statistics for em into sysctl tree.
- Reenable hardware checksum offload for VLAN frames in igb.
- Fix for a panic when TX checksum offload is done and a packet has only
  a header in the first mbuf in em.
