lfs: avoid a potential variable reference before assignment error in cmdserver
A coworker hit this once yesterday when pulling in thg (a retry worked), and
then I hit it with strip after a pull. I had a difficult time recreating a test
for this (at least one of the tricks was to not use '-R', which seems to cause
reposetup() to be called for each command), so I'm not sure how large of a
window there actually is for this. Calling reposetup() *after* the requirement
is added will skip the hook entirely.
The other issue I had was adding a couple `ui.status()` lines around the check
that installs the hook. On Windows, the cmdserver process ballooned to 1.6GB
and hung. Changing that to `ui.warn()` avoided the hang. It also hung on
macOS, but without the large memory usage.
