In the case of packed, use indirect desc, since desc is allocated by
kmalloc_array(), we should check whether its return value is NULL.

v4:
   Inside the #2 patch, virtqueue_add_indirect_packed() return -EAGAIN when
   desc == NULL.

v3:
    Update commit message of the #1 patch.

v2:
    Separate the style fix into a single patch.
