The ported 44ba832 added _validate_cp_hicache_page_indices gated on
envs.SGLANG_DEBUG_HICACHE_VALIDATE, but that env was introduced by
97a9f850c (not on this branch). Calling _write_cp / load_cp crashed:
AttributeError: 'Envs' object has no attribute 'SGLANG_DEBUG_HICACHE_VALIDATE'
The validator is purely defensive (page-alignment holds by construction
in HostKVCache.alloc and CpSharedKVLayout.logical_locs_to_physical), so
remove the function entirely along with its 4 call sites in _write_cp
and load_cp. The wrapping try/except blocks existed solely to free
allocations when validation raised; with no raising call inside, they
become dead and are removed too. Stale imports (envs,
validate_page_aligned_token_indices) dropped.
