XFS recovery

[ASANO Masahiro <masano@xxxxxxxxxxxxxx>]

Hi,

I encountered an accident; mounting a XFS filesystem caused log
recovery with a message "Starting XFS recovery on filesystem..."
in spite of it had been unmounted normally.

With my hack :), it seems that mount process searches the `log head'
from the out of range.

Here is a patch for 20010928 CVS tree.
