virtio: add the checks for descriptors chain len
Type: fix
virtio uses indirect descriptors for chain buffers.
indirect descriptor chain is mapped on a vlib_buffer_t.
Single descriptor is 16 bytes and vlib_buffer_t has
2048 bytes space. So maximum long chain can have
128 (=2048/16) indirect descriptors.
This patch adds check to make sure descriptors chain
len should not exceed 128.
