c03dbe8cc7 virtio-devices: block: Support multiple data descriptors 
The Windows virtio block driver puts multiple data descriptors between
the header and the status footer. To handle this when parsing iterate
over the descriptor chain until the end is reached accumulating the
address and length pairs in a vector. For execution iterate over the
vector and make sequential reads from the disk for each data descriptor.

b4f6db5f31 virtio-devices: vsock: Add 'brk' to the seccomp list 
We observed CI instability for the past couple of days. This
instability is confirmed to be a result of incomplete seccomp
filters. Given the filter on 'virtio_vsock' is recently added and
is missing 'brk', it is likely to be the root cause of the
instability.
