msm: secure_buffer: Ensure shared buffers are cache-aligned
Buffers shared with hypervisor might undergo some cache maintenance on
the hypervisor side. Currently, we're passing a buffer that might not
be cache-aligned (source_vm_list), so when the hypervisor does some
cache maintenance on it they might be corrupting data. Fix this by
ensuring that all buffers being shared with the hypervisor are
cache-aligned by kmalloc'ing and memcpy'ing the source_vm_list before
sending it across.
