Skip WAL recycling and preallocation during archive recovery. The previous commit addressed the chief consequences of a race condition between InstallXLogFileSegment() and KeepFileRestoredFromArchive(). Fix three lesser consequences. A spurious durable_rename_excl() LOG message remained possible. KeepFileRestoredFromArchive() wasted the proceeds of WAL recycling and preallocation. Finally, XLogFileInitInternal() could return a descriptor for a file that KeepFileRestoredFromArchive() had already unlinked. That felt like a recipe for future bugs.
