KVM: selftests: Add 'malloc' failure check in vcpu_save_state
[ Upstream commit 735b0e0f2d001b7ed9486db84453fb860e764a4d ]
There is a 'malloc' call in vcpu_save_state function, which can
be unsuccessful. This patch will add the malloc failure checking
to avoid possible null dereference and give more information
about test fail reasons.
