tracing: Add missing spaces in trace_print_hex_seq()
If the buffer length is larger than 16 and concatenate is set to false,
there would be missing spaces every 16 bytes.
Example:
Before: c5 11 10 50 05 4d 31 40 00 40 00 40 00 4d 31 4000 40 00
After: c5 11 10 50 05 4d 31 40 00 40 00 40 00 4d 31 40 00 40 00
