Before, we refreshed filters and we did full rescan of devices if we passed through wiping (wipe_known_signatures fn call). However, this fn returns success even if no signatures were found and so nothing was wiped. In this case, it's not necessary to do the filter refresh/rescan of devices as nothing changed clearly. This patch exports number of wiped signatures from all the wiping functions below. The caller (_pvcreate_check) then checks whether any wiping was done at all and if not, no refresh/rescan is done, saving some time and resources.
