Update ironware.rb

Some Brocade devices only have two possible fan speeds. Previously, this only handled three levels of fan speeds. Updated regex will handle both of these cases:

Fan 1 ok, speed (auto): 1<->[[2]]
Fan 1 ok, speed (auto): 1<->[[2]]<->3

perhaps cfg = cfg.tr('[]', '') if cfg.match(/^Fan /)would've been cleaner and more robust

or cfg = cfg.delete('[]') if cfg.match(/^Fan /)

aah both would require you parse the cfg line by line:

cmd 'blaah do |cfg|
  cfg.lines.map do |line|
    ! mangle lines here
  end.join
end
