[PATCH] extfs - do not enter broken archive

[Adam Byrtek 'alpha' <alpha student uci agh edu pl>]

When user entered archive and there was some problem with listing
archive contents (exit 1 in script) - user saw error and then empty
archive contents. After this patch he sees error, but is not moved
inside broken archive.

BTW when he tries to enter once more, this fix doesn't works - thanks
to vfs cache. Is the vfs cache really needed for local extfs
filesystems? For ftp or fish it's great, but local extfs' are quite
fast indeed...

Regards
