c++: Crash when deducing template arguments [PR98659]

maybe_instantiate_noexcept doesn't expect to see error_mark_node, but
the new callsite I introduced in r11-6476 can pass error_mark_node to
it.  So cope.

gcc/cp/ChangeLog:

PR c++/98659
* pt.c (maybe_instantiate_noexcept): Return false if FN is
error_mark_node.

gcc/testsuite/ChangeLog:

PR c++/98659
* g++.dg/template/deduce8.C: New test.
