Umesh Nerlige Ramappa e6e3ea52bf drm/xe/lrc: Fix uninitialized new_ts when capturing context timestamp
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.
