net/enic: suppress unwanted error messages

Do not log errors when CMD_OVERLAY_OFFLOAD_CTRL and
CMD_GET_SUPP_FEATURE_VER fail, as they are only used to probe if a
feature is provisioned. They are expected to fail if the feature is
not provisioned.

Do not log an error when disabling Geneve offload fails. It is
expected to fail if this feature is provisioned but not enabled.

Fixes: c02a96fc4aec ("net/enic: enable GENEVE with options offload")
