Xiaomeng Tong 259773fc87 virtio-gpu: fix a missing check to avoid NULL dereference 
[ Upstream commit bd63f11f4c3c46afec07d821f74736161ff6e526 ]

'cache_ent' could be set NULL inside virtio_gpu_cmd_get_capset()
and it will lead to a NULL dereference by a lately use of it
(i.e., ptr = cache_ent->caps_cache). Fix it with a NULL check.

Fixes: 62fb7a5e10962 ("virtio-gpu: add 3d/virgl support")
