f2fs: fix submit accounting for IPU writeback

f2fs_write_cache_pages() uses the submitted count, which is set to
fio.submitted in f2fs_write_single_data_page(), to update nwritten
and decrement wbc->nr_to_write.

In the OPU path, f2fs_submit_page_write() sets fio->submitted to 1.
However, in the IPU path, fio->submitted is never set and remains zero.
As a result, successful IPU writes are not accounted for.
This can cause asynchronous writeback to continue beyond its budget.

Set fio->submitted in f2fs_inplace_write_data() after a page is
successfully merged into a bio or submitted, so that successful
IPU writes are included in the writeback accounting.
