drm/shmem: Add docbook comments for drm_gem_shmem_object madvise fields 

Add missing docbook comments to madvise fields in struct
drm_gem_shmem_object which fixes these warnings:

include/drm/drm_gem_shmem_helper.h:87: warning: Function parameter or member 'madv' not described in 'drm_gem_shmem_object'
include/drm/drm_gem_shmem_helper.h:87: warning: Function parameter or member 'madv_list' not described in 'drm_gem_shmem_object'

Fixes: 17acb9f35e ("drm/shmem: Add madvise state and purge helpers")
