gpu: nvgpu: Change va_node free behavior
Decrement the ref count on all mapped_buffers belonging to a va_node
when a va_node is freed. This prevents userspace from leaking some
mapped_buffers in some cases.
This does prevent userspace from keeping a buffer around after freeing
a space allocation if the buffer in question is not otherwise ref
counted. Not sure if this is a bad thing for userspace or not.
