Since the new capability KVM_DIRTY_LOG_INITIALLY_SET of
KVM_CAP_MANUAL_DIRTY_LOG_PROTECT2 has been introduced, tweak the
clear_dirty_log_test to test it.

Thanks, instead of this final "if" it should be enough to do
dirty_log_manual_caps &= (KVM_DIRTY_LOG_MANUAL_PROTECT_ENABLE |
KVM_DIRTY_LOG_INITIALLY_SET);
Otherwise looks good, I'll test it and eventually apply both patches.
