Fix #114: remove redundant initial state check in LC_SampleAPs

[philphauler]

Summary

Remove the redundant guard on the starting AP state in LC_SampleAPs.

Problem

LC_SampleAPs(StartIndex, EndIndex) checks ARTPtr[StartIndex].CurrentState
before entering the sampling loop. If the first AP is PERMOFF or NOT_USED,
the entire range is skipped and an error event is emitted -- even though
subsequent APs in the range may be operational.

LC_SampleSingleAP already checks each AP state individually, making this
pre-check redundant and harmful when a range begins with a disabled AP.

Fix

Remove the pre-check. Let LC_SampleSingleAP handle per-AP state filtering
for each action point in the range. Net deletion of 21 lines.

[philphauler]

Removes a redundant initial-state check that LC_SampleSingleAP already handles per-AP. 6 lines added, 27 removed. No behavioral change — the per-AP handler covers all cases.
