V4L/DVB (6082): cx88: Improve risc instruction printing in sram channel dump

When the risc instrunctions from the CMDS were printed, instruction arguments
weren't taken into account.

This changes output like:
cx88[0]:   risc0: 0x1d010400 [ write sol eol irq1 cnt0 count=1024 ]
cx88[0]:   risc1: 0x0cac2800 [ INVALID sol eol 23 21 19 18 13 count=2048 ]
cx88[0]:   risc2: 0x1d010400 [ write sol eol irq1 cnt0 count=1024 ]
cx88[0]:   risc3: 0x0cac2c00 [ INVALID sol eol 23 21 19 18 13 count=3072 ]

cx88[0]:   risc0: 0x1d010400 [ write sol eol irq1 cnt0 count=1024 ]
cx88[0]:   risc1: 0x0cac2800 [ arg #1 ]
cx88[0]:   risc2: 0x1d010400 [ write sol eol irq1 cnt0 count=1024 ]
cx88[0]:   risc3: 0x0cac2c00 [ arg #1 ]
