Maxime Coquelin 612e17cf6d vhost: fix possible denial of service on SET_VRING_NUM 
vhost_user_set_vring_num() performs multiple allocations
without checking whether data were previously allocated.

It may cause a denial of service because of the memory leaks
that happen if a malicious vhost-user master keeps sending
VHOST_USER_SET_VRING_NUM request until the slave runs out
of memory.

This issue has been assigned CVE-2019-14818

Fixes: b0a985d1f3 ("vhost: add dequeue zero copy")
