[PATCH 1/2] qemu: fix some small issue in qemuProcessAttach

[Luyao Huang <lhuang@xxxxxxxxxx>]

There are some small issue in qemuProcessAttach:

1.Fix virSecurityManagerGetProcessLabel always get pid = 0,
move 'vm->pid = pid' before call virSecurityManagerGetProcessLabel.

2.Use virSecurityManagerGenLabel to get image label.

3.Fix always set selinux label for other security driver label.
