In the case of packed, use indirect desc, since desc is allocated by
kmalloc_array(), we should check whether its return value is NULL.
This patch alloc desc inside virtqueue_add_packe(), if desc == NULL,
fall back to not using indirect.
v3:
Update commit message of the #1 patch.
v2:
Separate the style fix into a single patch.
Xuan Zhuo (2):

virtio_ring: check desc == NULL when packed and indirect
