Getting engine specific CTX TIMESTAMP register can fail. In that case,
if the context is active, new_ts is uninitialized. Fix that case by
initializing new_ts to the last value that was sampled in SW -
lrc->ctx_timestamp.
Flagged by static analysis.

Problem: individual swidle counter names (C1, C1+, C1-, etc.) cannot be

1. The function returns immediately when BIC_cpuidle is not enabled,
without checking deferred_add_index.
