drm/xe/uapi: Fix kernel-doc formatting for madvise and vma_query

Correct kernel-doc formatting issues in the UAPI definitions for
madvise and VMA query interfaces to resolve docutils warnings during
documentation build.

Fixes: 4188078 ("drm/xe/uapi: Add UAPI for querying VMA count and memory attributes")
Fixes: 231bb0e ("drm/xe/uapi: Add madvise interface")
