video: tegra: nvmap: Clear handle->owner on release

A struct nvmap_handle may be shared by multiple clients.  If the
original client (the handle "owner") is destroyed, but the handle is
still referenced by other clients, h->owner points to freed memory.  To
prevent this, clear h->owner when the owner frees its reference to that
struct nvmap_handle.
