uprobes/x86: Fix arch_uprobe_disable_step() && UTASK_SSTEP_TRAPPED interaction
arch_uprobe_disable_step() should also take UTASK_SSTEP_TRAPPED into account. In this case the probed insn was not executed, we need to clear X86_EFLAGS_TF if it was set by us and that is all. Again, this code will look more clean when we move it into arch_uprobe_post_xol() and arch_uprobe_abort_xol().
