Revert "f2fs: node segment is prior to data segment selected victim"

This reverts commit b9cd20619e359d199b755543474c3d853c8e3415.

That patch causes much fewer node segments (which can be used for SSR)
than before, and in the corner case (e.g. create and delete *.txt files in
one same directory, there will be very few node segments but many data
segments), if the reserved free segments are all used up during gc, then
the write_checkpoint can still flush dentry pages to data ssr segments,
but will probably fail to flush node pages to node ssr segments, since
there are not enough node ssr segments left (the left ones are all
full).

So revert this patch to give a fair chance to let node segments remain
for SSR, which provides more robustness for corner cases.
