f2fs: disallow setting an extension to both cold and hot

Browse source

An extension should not exist in both the cold and hot extension lists
simultaneously. When adding a hot extension, check whether it already
exists in the cold list, and vice versa. Reject the operation with
-EINVAL if a conflict is found.
