Dorinda Bassey ab67c542a9 virtio-dmabuf: Ensure UUID persistence for hash table insertion 
In `virtio_add_resource` function, the UUID used as a key for
`g_hash_table_insert` was temporary, which could lead to
invalid lookups when accessed later. This patch ensures that
the UUID remains valid by duplicating it into a newly allocated
memory space. The value is then inserted into the hash table
with this persistent UUID key to ensure that the key stored in
the hash table remains valid as long as the hash table entry
exists.
