Update ios.rb

[dpombo]

Replace:
cfg.gsub! /^ tunnel mpls traffic-eng bandwidth[^\n]\n(
(?: [^\n]\n)*
tunnel mpls traffic-eng auto-bw)/mx, '\1'

by:

This removes 'bandwidth X' only if 'auto-bw' is configured in the same interface

  cfg.gsub! /^ (tunnel mpls traffic-eng bandwidth [^\n]*)\n((?: [^\n]*\n)* tunnel mpls traffic-eng auto-bw)/, '\2'
