virtqueue: Fix comment on shm_io and fix type

Browse Source 
This should hold a pointer to a metal_io_region, make that the type.

Also fix the comment above this variable. This region holds the address
of the message buffers, not the vring descriptor table nor available/used
ring data. It is only used for virt-to-phys/phys-to-vert translation on
the buffers pointed to by these descriptors.
