From: zangyangyang1 <zangyangya...@xiaomi.com>
When f2fs_write_single_data_page fails, f2fs_write_cache_pages
will use the last 'submitted' value incorrectly, which will cause
'nwritten' and 'wbc->nr_to_write' calculation errors
Signed-off-by: zangyangyang1 <zangyangya...@xiaomi.com>

v4: The Callers initializes it
v3: No logical changes, just format patch
v2: Initialize "submitted" in f2fs_write_single_data_page()
