Ashutosh Desai 03e8578813 rust: sync: add #[must_use] to GlobalGuard and GlobalLock::try_lock
Guard is marked #[must_use] since dropping it releases the lock. GlobalGuard
wraps Guard with identical semantics but was missing the annotation, so
discarding it would silently compile without warning.

Similarly, GlobalLock::try_lock was missing #[must_use]. Option<T> does not
propagate #[must_use] from T, so the attribute needs to be on the function
directly - same reason Lock::try_lock has it.
