md: add a new parameter 'offset' to md_super_write()

Browse source

The parameter is always set to 0 for now, following patches will use
this helper to write llbitmap to underlying disks, allow writing
dirty sectors instead of the whole page.

Also rename md_super_write to md_write_metadata since there is nothing
super-block specific.
