Romain Baugue b6ec56bc26 encoding/json: don't indirect pointers when decoding null
The indirect method checked the type of the child when indirecting a
pointer. If the current value is a pointer and we are decoding null, we
can skip this entirely and return early, avoiding the whole descent.

Fixes #31776
