lib/hexdump: print_hex_dump_bytes() calls print_hex_dump_debug()

print_hex_dump_bytes() claims to be a simple wrapper around
print_hex_dump(), but it actally calls print_hex_dump_debug(), which
means no output is printed if (dynamic) DEBUG is disabled.

Update the documentation to match the implementation.
