test(memory share): retrieve request from VM

The SPMC supports the case in which the hypervisor doesn't
track the operation. This is usable for multiple borrower operations,
with a VM. In this case, hypervisor/OS Kernel shall forward the
requests to retrieve memory into the SPMC. This patch adds such
case, as we lost this coverage in the Hafnium tests.
