Currently, we use f2fs_has_inline_xattr() to check whether the
inode can store inline xattr. However, it might be misinterpreted
as the inode has at least one inline xattr.
The same is true for f2fs_has_inline_data() and
f2fs_has_inline_dentry(). To be more intuitive and specific,
refine comments of inline flags.
