builtin/pack-objects.c: avoid redundant NULL check

Before calling `for_each_object_in_pack()`, the caller
`read_packs_list_from_stdin()` loops through each of the `include_packs`
and checks that its `->util` pointer (which is used to store the `struct
packed_git *` itself) is non-NULL.

This check is redundant, because `read_packs_list_from_stdin()` already
checks that the included packs are non-NULL earlier on in the same
function (and it does not add any new entries in between).

Remove this check, since it is not doing anything in the meantime.
