[PATCH 7/9] isosize: move file name printing after error determination

[Sami Kerola <kerolasa@iki.fi>]

Earlier the filename printing was buffered, and exit at error made output
to appear in front of prompt.  Output below demonstrates the brokenness.

prompt> isosize /etc /
isosize: /etc: might not be an ISO filesystem
isosize: read error on /etc: Is a directory
/etc: prompt>
