Nouveau - Oct 2023 - [PATCH v2] drm/nouveau: exec: fix ioctl kernel-doc warning

kernel-doc emits a warning:

include/uapi/drm/nouveau_drm.h:49: warning: Cannot understand  *
@NOUVEAU_GETPARAM_EXEC_PUSH_MAX
 on line 49 - I thought it was a doc line

We don't have a way to document a macro value via kernel-doc, so
change the "/**" kernel-doc marker to a C comment and format the
comment
more like a kernel-doc comment for consistency.

Fixes: d59e75eef52d ("drm/nouveau: exec: report max pushs through
getparam")
