[053/128] KVM: selftests: Convert svm_int_ctl_test away from VCPU_ID

Commit Message

Sean Christopherson May 4, 2022, 10:47 p.m. UTC

Convert svm_int_ctl_test to use vm_create_with_one_vcpu() and pass around
a 'struct kvm_vcpu' object instead of using a global VCPU_ID.

Opportunistically make the "vm" variable a local function variable, there
are no users outside of main().
