Fix afs_launder_page() to set the starting position of the StoreData RPC at
the offset into the page at which the modified data starts instead of at
the beginning of the page (the iov_iter is correctly offset).
The offset got lost during the conversion to passing an iov_iter into
afs_store_data().
Fixes: bd80d8a80e12 ("afs: Use ITER_XARRAY for writing")
