Log Message:
Pull up following revision(s) (requested by hannken in ticket #162):
        sys/dev/vnd.c: revision 1.220
        sys/dev/vndvar.h: revision 1.32
When backed by a sparse file limit the number of pending requests.
Should fix PR #45829: "writing to vnd on sparse file blocks on pager_map"
where the pager_map gets exhausted by requests enqueued on a vnd
device and the device worker thread blocks on putpages() needing the map.
While here always sync the underlying vnode before calling biodone().
XXX: vnd should be converted to mutex/condvar.
