When printing a pointer value, "%p" will either print the hexadecimal
value of the pointer (e.g `0x1234`), or `(nil)` when NULL.
Both of those are invalid json "integer" values and need to be wrapped
in quotes.
Before:
```
$ sudo bpftool struct_ops dump name ned_dummy_cca | grep next
"next": (nil),
$ sudo bpftool struct_ops dump name ned_dummy_cca | \
jq '.[1].bpf_struct_ops_tcp_congestion_ops.data.list.next'
parse error: Invalid numeric literal at line 29, column 34
```
After:
```
$ sudo ./bpftool struct_ops dump name ned_dummy_cca | grep next
"next": "(nil)",
$ sudo ./bpftool struct_ops dump name ned_dummy_cca | \
jq '.[1].bpf_struct_ops_tcp_congestion_ops.data.list.next'
"(nil)"
```
