2462656f21 [user/ls]: List specific device file 
When using the ls userspace program to list a specific device file,
nothing would be displayed. This was because ls only tests for T_FILE
and T_DIR. T_DEVICE files would fall through the case block.

Adding T_DEVICE to the T_FILE case allows a device file to be listed.

    $ ls console
    console        3 19 0
