vsock/vmci: convert VMCI error code to -ENOMEM on send

This adds conversion of VMCI specific error code to general -ENOMEM. It
is needed, because af_vsock.c passes error value returned from transport
to the user, which does not expect to get VMCI_ERROR_* values.

Fixes: c43170b ("vsock: return errors other than -ENOMEM to socket")
