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.
