Fix code for disabling mirrors on network errors

The idea is to try each mirror in order, but when one fails
with a network error we mark it so we don't keep trying on
each dependency. The logic was wrong in that it marked the
entire entry (consisting of multiple mirrors) instead of
marking mirrors individually.

Closes #1179.
