f2fs: do not skip writing data pages
For data pages, let's try to flush as much as possible in background.
On /dev/pmem0,
1. dd if=/dev/zero of=/mnt/test/testfile bs=1M count=2048 conv=fsync
Before : 800 MB/s
After : 1.1 GB/s
2. dd if=/dev/zero of=/mnt/test/testfile bs=1M count=2048
Before : 1.3 GB/s
After : 2.2 GB/s
