zebra: Allow interface up events to read speed

Initially the reading of the speed of an interface happened
upon interface creation and happened until the speed of a link
settled down to a single value.  The speed of an interface
can also change as that a new optic can be inserted that
changes the speed, in which case FRR would see a interface
down (optic removal) and then a interface up (optic insertion).

In this case FRR would not treat this as an event that changed
the speed.  Let's expand the checking a bit more.
