Change the parameter type of smp_debug_print_nbyte_little_endian

Change the parameter type of smp_debug_print_nbyte_little_endian

* This function used to take (const uint8_t*) as the second parameter
  and it causes all its calls to cast a (const char*) to this type
* This patch changes it to (const char*) so no cast needed

Coccinelle-assisted:

@ rule1 @
type T;
expression A, B, C;
@@

smp_debug_print_nbyte_little_endian(A,
- (T)
B, C);

and

for file in $(find . -name "*.cc"); do
  spatch --sp-file refactor_smp_print_func.cocci --in-place $file
done
