[PATCH 05/11] kvm, x86: introduce kvm_inject_x86_mce_on

[Jin Dongming <jin.dongming@xxxxxxxxxxxxxxxxxx>]

Pass a table instead of multiple args.

Note:

kvm_inject_x86_mce(env, bank, status, mcg_status, addr, misc,
                   abort_on_error);

is equal to:

struct kvm_x86_mce mce = {
    .bank = bank,
    .status = status,
    .mcg_status = mcg_status,
    .addr = addr,
    .misc = misc,
};
kvm_inject_x86_mce_on(env, &mce, abort_on_error);
