In many places where we are calling down into virtchnl, we are using a

Changes from v1:
Stats query was passing in a pointer-to-pointer and storing pointer to
global adminq response buffer as output parameter, so changing that to a
local buffer resulted in storing a pointer to a buffer that was stack
allocated (i.e. introduced a use-after-free).
I've changed that to allocate the stats structure on the stack and write
into that, instead of returning a pointer to output buffer and reading
from it.
