tests/scsi_recovery.rs: - Add `use std::time::Duration` inside both `#[cfg(target_os = "linux")]` blocks. Locally on macOS the linux blocks are cfg-out so the missing import was invisible to precommit on macOS. - Bug pre-dated this branch but only surfaced when v0.17.2 release CI ran the test compile on Linux. Cargo.toml: 0.17.2 -> 0.17.3.
