f2fs: compress: remove unneeded read when rewrite whole cluster
[ Upstream commit 7eab7a6968278c735b1ca6387056a408f7960265 ]
when we overwrite the whole page in cluster, we don't need read original
data before write, because after write_end(), writepages() can help to
load left data in that cluster.
