Prevent a double open. This can cause problems with some ieee1275
devices, causing the system to hang. The double open can occur
as follows:
grub_ls_list_files (char *dirname, int longlist, int all, int human)
dev = grub_device_open (device_name);
dev remains open while:
grub_normal_print_device_info (device_name);
dev = grub_device_open (name);
