vhost: Cache qsz_mask instead of qsz in vhost_user_vring_t
In the data path, we grab qsz from vhost_user_vring_t to compute qsz_mask and store it in a stack variable to use on many occasions. We never use qsz for any meaningful purpose. It is more useful to cache qsz_mask in vhost_user_vring_t to avoid the needless computation in the data path.
