f2fs: try to flush inode after merging inline data

When flushing node pages, if current node page is an inline inode page, we
will try to merge inline data from data page into inline inode page, then
skip flushing current node page, it will decrease the number of nodes to
be flushed in batch in this round, which may lead to worse performance.

This patch gives a chance to flush just merged inline inode pages for
performance.
