Subject: [PATCH v4.1 2/3] KVM: selftests: Add #define of expected KVM exit
 reason for ucall

Precedence: bulk

Define the expected architecture specific exit reason for a successful
ucall so that common tests can assert that a ucall occurred without the
test needing to implement arch specific code.
