panvk/jm: Preload the FB even if we have no draws queued

Browse Source 
There seems to be cases where we end up with a depth/stencil preload,
with no draw associated to it, so let's make sure we preload in that
case, otherwise we will write invalid data back.

Fixes: 0bc3502ca3 ("panvk: Implement a custom FB preload logic")
