glusterd: Restarting glusterd should not reset bitrot tunable value to default

Previously when user restart glusterd then bitrot tunable value for option
"scrub-throttle", "scrub-frequency", "scrub" cleared. glusterd was not storing
these bitrot tunable value properly.

With this fix it will store scrub-throttle, scrub-frequency, scrub, bitrot
tunable value in /var/lib/glusterd/vols/<volname>/info file and it will resume
these value when glusterd restart.
