[dpdk-dev] [PATCH 1/4] common/iavf: fix duplicate defined offload bit

The value of offload VIRTCHNL_VF_OFFLOAD_CRC bit already existed as
VIRTCHNL_VF_CAP_ADV_LINK_SPEED. Fix this now by changing the value of
VIRTCHNL_VF_OFFLOAD_CRC to a currently unused value.

Also, move the define for VIRTCHNL_VF_CAP_ADV_LINK_SPEED in the correct
place to line up with the other bit values and add a comment for its
purpose. Hopefully this will prevent from defining duplicate bits moving
forward.
