xz: fix kernel-doc formatting errors in xz.h

The opaque structs xz_dec and xz_dec_microlzma are declared in xz.h but
their definitions are in xz_dec_lzma2.c without kernel-doc comments.  Use
regular comments for these structs in xz.h to avoid errors when building
the docs.

Add a few missing colons.
