ext4: tidy up a void argument in inode.c

This doesn't fix anything at all, it just removes a vestige
of prior use from __mpage_da_writepage()

__mpage_da_writepage() had a *void argument leftover from
its previous life as a callback; make it reflect the actual type.

Fixing this up makes it slightly more obvious to read, and 
enables proper typechecking.
