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.
