Robert Wing 20123b25ee fsck_ffs(8): fix divide by zero when debug messages are enabled
Only print buffer cache debug message when a cache lookup has been done.

When running `fsck_ffs -d` on a gjournal'ed filesystem, it's possible
that totalreads is greater than zero when no cache lookup has been
done - causing a divide by zero. This commit fixes the following error:

    Floating point exception (core dumped)
