rGe36a6b1b1f39: if_vtnet: Add support for CTRL_GUEST_OFFLOADS feature

Summary

This allows the Rx checksum and LRO to be modified without a full
reinit of the device.

Remove IFCAP_RXCSUM_IPV6 from the interface capabilities since in
VirtIO Rx checksums are just enabled or disabled for all protocols.

Properly update IFCAP_LRO if LRO is becomes disabled when Rx
checksums are disabled.
