c++: Fix nullptr deref [pr97460[

My changes to friend handling meant that there are now cases where a
friend doesn't get a lang-specific object.  So we need to check there
is one before looking inside it.

PR c++/97460
gcc/cp/
* pt.c (push_template_decl): Check DECL_LANG_SPECIFIC in friend
case.
gcc/testsuite/
* g++.dg/template/pr97460.C: New.
