f2fs: split UMOUNT and FASTBOOT flags
This patch adds FASTBOOT flag into checkpoint as follows. - CP_UMOUNT_FLAG is set when system is umounted. - CP_FASTBOOT_FLAG is set when intermediate checkpoint having node summaries was done. So, if you get CP_UMOUNT_FLAG from checkpoint, the system was umounted cleanly. Instead, if there was sudden-power-off, you can get CP_FASTBOOT_FLAG or nothing.
