    camcontrol: dump received data for MMC command even if it is unknown
    
    For example, EXT_CSD can be read like this:
        # camcontrol mmcsdcmd 2:0:0 -c 8 -a 0 -f 0x35 -l 512
        CMD 8 arg 0 flags 35
        MMCIO: error 0, 00000900 00000000 00000000 00000000
        No command-specific decoder for CMD 8
