Carefully set IFF_OACTIVE in mvgbe_start(). Even if mvgbe_encap()
returns other than 0, the TX ring might not full. Check whether
the TX ring has one or more packets. If the ring is empty,
dont' set IFF_OACTIVE because an TX complete interrupt never
occur and IFF_OACTIVE flags is left. The interface's timer
isn't reset, so a device timeout desn't occur.
Fixes a bug that IFF_OACTIVE flag is left on heavy load.
