c-family: Fix ICE with -Wsuggest-attribute [PR98487]
Here we crash because check_function_format was using TREE_PURPOSE
directly rather than using get_attribute_name.
PR c/98487
gcc/c-family/ChangeLog:
* c-format.cc (check_function_format): Use get_attribute_name.
gcc/testsuite/ChangeLog:
* c-c++-common/Wsuggest-attribute-1.c: New test.
