The Vhost-user backend implementation assumes there will be
no holes in the device's array of virtqueues metadata
pointers.
It can happen though, and would cause segmentation faults,
memory leaks or undefined behaviour.
This patch keep the assumption that there is no holes in this
array, and allocate all uninitialized virtqueues metadata up
to requested index.
