MemorySanitizer: use-of-uninitialized-value (probably false positive)

[PSeitz]

Note: This is probably a false positive, since C++ dependencies need to be compiled with sanitization flags (https://doc.rust-lang.org/beta/unstable-book/compiler-flags/sanitizer.html#memorysanitizer). This issue is just to keep track of it, as this would be serious. Here it seems we need to compile zstd with sanitization.

Reproducible on main branch with:
RUSTFLAGS=-Zsanitizer=memory cargo +nightly test -Zbuild-std --target x86_64-unknown-linux-gnu test_fast_field_range -- --nocapture

Bisected to 780e263
