[PATCH v2 08/16] docs: Add XZ_EXTERN to c_id_attributes

[Lasse Collin <lasse.collin@xxxxxxxxxxx>]

include/linux/xz.h uses XZ_EXTERN in function prototypes. It's needed in
the preboot code. Adding XZ_EXTERN c_id_attributes silences warnings and
makes the intradocument links to the xz_dec functions work.
