ip/xfrm: Fix potential SIGSEGV when printing extra flags

The git-commit dc8867d0, that added support for displaying the
extra-flags of a state, introduced a potential segfault.
Trying to show a state without the extra-flag attribute and show_stats
enabled, would cause the NULL pointer in tb[XFRMA_SA_EXTRA_FLAGS] to be
dereferenced.
