[PATCH v3 3/3] Use startup_info->prefix rather than prefix.

[Jared Hance <jaredhance@gmail.com>]

In trace_repo_setup, prefix is passed in as startup_info->prefix. But, as
indicated but a FIXME comment, trace_repo_setup has access to
startup_info. The prefix parameter has therefore been eliminated.
