vhost: use struct_size and size_add to compute flex array sizes
The vhost_get_avail_size and vhost_get_used_size functions compute the size
of structures with flexible array members with an additional 2 bytes if the
VIRTIO_RING_F_EVENT_IDX feature flag is set. Convert these functions to use
struct_size() and size_add() instead of coding the calculation by hand.
This ensures that the calculations will saturate at SIZE_MAX rather than
overflowing.
