The current log message results in a line like the following where
the first byte is duplicated, giving a wrong impression:
sd 0:0:0:0: [sda] tag#0 CDB: opcode=0x28 28 00 00 00 60 40 00 00 01 00
Print the cdb into a new line in any case, not only when cmd_len is
greater than 16. The above example error will then read:
sd 0:0:0:0: [sda] tag#0 CDB: opcode=0x28
28 00 01 c0 09 00 00 00 08 00
