Allow users to create a QP that uses cvlan stripping capabilities if
supported by the hardware.

Setting cvlan stripping offload will cause the device to strip the
cvlan from incoming raw Ethernet packets and provide its data in the
matching work completion.

In addition, aligned ibv_create_qp_ex's man page with current code
(added ibv_qp_create_flags enum).
