f2fs: clean up lfs/adaptive mount option
This patch removes F2FS_MOUNT_ADAPTIVE and F2FS_MOUNT_LFS mount options,
and add F2FS_OPTION.fs_mode with below two status to indicate filesystem
mode.
enum {
FS_MODE_ADAPTIVE, /* use both lfs/ssr allocation */
FS_MODE_LFS, /* use lfs allocation only */
};
It can enhance code readability and fs mode's scalability.
