octeontx2-pf: Send UP messages to VF only when VF is up.
[ Upstream commit dfcf6355f53b1796cf7fd50a4f27b18ee6a3497a ]
When PF sending link status messages to VF, it is possible
that by the time link_event_task work function is executed
VF might have brought down. Hence before sending VF link
status message check whether VF is up to receive it.
