block_connected: re-use previous GetTimeMicros

Shave off an extra 100 or so instructions from the
validation:block_connected tracepoint by reusing a nearby
GetTimeMicros(). This brings the tracepoint down to 54 instructions.
Still high, but much better than the previous ~154 and 8000 instructions
which it was originally.
