[PULL 5/8] tests/functional/asset: Fail assert fetch when retries are exceeded

[Thomas Huth <thuth@redhat.com>]

From: Nicholas Piggin <npiggin@gmail.com>

Currently the fetch code does not fail gracefully when retry limit is
exceeded, it just falls through the loop with no file, which ends up
hitting other errors.

Add a check for non-existing file, which indicates the retry limit was
exceeded.
