[PATCH] xen/shbuf: eliminate 17 kernel-doc warnings

[Randy Dunlap <rdunlap@xxxxxxxxxxxxx>]

Don't use kernel-doc markers ("/**") for comments that are not in
kernel-doc format. This prevents multiple kernel-doc warnings:

xen-front-pgdir-shbuf.c:25: warning: This comment starts with '/**', but isn't 
a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
 * This structure represents the structure of a shared page

 * Shared buffer ops which are differently implemented
