## Issue
Deadlock while performing reingestion in the DR for pauseless.
## Details
- Reingestion of `ERROR` segments while fixing pauseless tables acquires
segBuildSemaphore
- The segBuildSemaphore was not released
- This was causing threads to indefinitely wait to build segments.
- Helix state transitions rely on segment lock.
- Segment lock is also attained in `RealtimeSegmentDataManager` before
building the segment.
- Thus, the state transitions also got blocked hogging all the helix
state transition threads.
- This paused ingestion for normal tables as well.
