Fix a link state issue reported by reyk@

In some situations we were not clearing pending link state attentions.
Because of this we were not getting further interrupts for link state
changes, thus never went into iface UP state.

Force an interrupt at the end of bge_ifmedia_upd so we will call
bge_link_upd, clear the link state attention and get further
interrupts.
