lib/generic/pack: fix operations on empty pack

Several operations were not safe to call on empty pack and would
return invalid memory. If the pack would have reserved space, but
would be empty (length = 0), it's head would be NULL but tail would
be array address (pack->at + 0). This is mostly checked by caller,
but it wasn't in several places (object deletion).
