commit c4ef867f2949bf2a2ae18a4e27cf1a34bbc8aecb
Author: Ray Zhang <zhanglei002@gmail.com>

target/i386/kvm: fix kvmclock_current_nsec: Assertion `time.tsc_timestamp <= migration_tsc' failed
New KVM_CLOCK flags were added in the kernel.(c68dc1b577eabd5605c6c7c08f3e07ae18d30d5d)
```
+ #define KVM_CLOCK_VALID_FLAGS \
+ (KVM_CLOCK_TSC_STABLE | KVM_CLOCK_REALTIME | KVM_CLOCK_HOST_TSC)
case KVM_CAP_ADJUST_CLOCK:
- r = KVM_CLOCK_TSC_STABLE;
+ r = KVM_CLOCK_VALID_FLAGS;
```
kvm_has_adjust_clock_stable needs to handle additional flags,
so that s->clock_is_reliable can be true and kvmclock_current_nsec doesn't need to be called.
