KVM: selftests: Don't set reserved bits for invalid Hyper-V hypercall number

Browse source

Bits 27 through 31 in Hyper-V hypercall 'control' are reserved (see
HV_HYPERCALL_RSVD0_MASK) but '0xdeadbeef' includes them. This causes
KVM to return HV_STATUS_INVALID_HYPERCALL_INPUT instead of the expected
HV_STATUS_INVALID_HYPERCALL_CODE.
