storage: drop 'Extent' from virStorageBackendWipeExtentLocal

Browse Source 
The only caller always passes 0 for the extent start.
Drop the 'extent_start' parameter, as well as the mention of extents
from the function name.

Change off_t extent_length to unsigned long long wipe_len, as well as the
'remain' variable.
