bitrot: getting correct value of scrub stat's

When user execute bitrot scrub status command then gluster
is not giving correct value of Number of Scrubbed files,
Number of Unsigned files, Last completed scrub time,
Duration of last scrub.

With this patch scrub status will give correct value for
all the above fields.
