Martin Ågren 837e34eba4 treewide: prefer lockfiles on the stack 
There is no longer any need to allocate and leak a `struct lock_file`.
The previous patch addressed an instance where we needed a minor tweak
alongside the trivial changes.

Deal with the remaining instances where we allocate and leak a struct
within a single function. Change them to have the `struct lock_file` on
the stack instead.

These instances were identified by running `git grep "^\s*struct
lock_file\s*\*"`.
