ui: remove unnecessary boolean check

This check was added in 3c31c34 when the kernel module loader was
introduced into the app lifecycle, to avoid attempting to start a root shell
twice. When the module loader was removed in a03ad51, this flag
was accidentally left in when it should have been deleted.
