Fix a merge error in conf-sanity.sh. Using CMDVERBOSE this way was

passing "> /dev/null" as an extra argument to the functions, and this
is not really what we want.  Since I don't think it's all that bad to
see the output of lconf, anyway, I just deleted the >/dev/null
entirely.

While looking into this, I also noticed that mount -f was still
attempting to fetch the log from the MDS. That is fixed, too.
