storage: Attempt to refresh volume after successful wipe volume

Browse Source 
https://bugzilla.redhat.com/show_bug.cgi?id=1270709

When a volume wipe is successful, perform a volume refresh afterwards to
update any volume data that may be used in future volume commands, such as
volume resize.  For a raw file volume, a wipe could truncate the file and
a followup volume resize the capacity may fail because the volume target
allocation isn't updated to reflect the wipe activity.
