impr: Fix ptrdiff_t print formatting

ipmr_vif_seq_show() prints the difference between two pointers with the format string %2zd (z for size_t), however the correct format string is %2td instead (t for ptrdiff_t).

The same bug in ip6mr_vif_seq_show() was already fixed long ago by commit d430a227d272 ("bogus format in ip6mr").
