clone: warn on failure to repo_init()

The --bundle-uri option was added in 5556891961 (clone: add
--bundle-uri option, 2022-08-09), but this also introduced a call to
repo_init() whose return value was ignored. Fix that ignored value by
warning that the bundle URI process could not continue if it failed.
