Disable safemode prompting. When safemode discovers that one or more
fuse bits have unintentionally changed, it will prompt for
confirmation regarding whether or not it should attempt to recover the
fuse bit(s). Specifying this flag disables the prompt and assumes
that the fuse bit(s) should be recovered without asking for
confirmation first.
