f2fs: don't submit irrelevant page

Browse source

While we call ->writepages, there are two cases:
a. we didn't writeout any dirty pages, since they are writebacked by other
thread concurrently.
b. we writeout dirty pages, and have already submitted bio to block layer.

In these cases, we don't need to do additional bio flushing unnecessarily,
it may split bio in cache into smaller one.
