[PATCH] fetch2: Improve mirror building function error handling

[PATCH] fetch2: Improve mirror building function error handling

[Richard Purdie]

First, when building mirror urls we don't do any fetching so we should never
be calling clean functions.

Currently, if a mirror url fails, we don't process it further to see
if there are any mirrors of the mirror.

We should do this even when the mirror url fails, else we may miss out
on valid/useful mappings, particularly in the case of file:// urls.
