iolog: fix reported defect from coverity scan

Fix the two Null pointer dereferences issue reported by Coverity scan Null pointer dereferences (FORWARD_NULL) Dereferencing null pointer "l->td" Null pointer dereferences (REVERSE_INULL) Null-checking "p->td" suggests that it may be null, but it has already been dereferenced on all paths leading to the check.
