Similar to the previous commits, avoid peeking into the `struct
lock_file`. Use the lock file API instead.

The two functions we're calling here double-check that the tempfile is
indeed "active", which is arguably overkill considering how we took the
lock on the line immediately above. More importantly, this future-proofs
us against, e.g., other code appearing between these two lines or the
lock file and/or tempfile internals changing.
