* kernel: Fixed hook type and KPM status retrieval errors

* kernel: Fixed potential null pointer issue with current->mm in kernel version 5.10

When calling get_full_comm() within system call hooks, current->mm may be null (prctl). A fallback mechanism for current->comm must be added beforehand to prevent null pointer dereferences when accessing mm->arg_start/arg_end.
