Fix overflow of kSeedMask on 32 bits platform in `generate_new_seed`.

`data_ = (data_ & ~kSeedMask) | (seed & kSeedMask);` was clearing top 32 bits. Somehow that was happening only in ASAN 32 bits. On non-asan builds the compiler was "optimizing" to be correct.

The bug was reported by chromium: https://g-issues.chromium.org/issues/402910364.
