attribs: Don't diagnose attribute exclusions during error recovery [PR94705]
On the following testcase GCC ICEs, because last_decl is error_mark_node,
and diag_attr_exclusions assumes that if it is not NULL, it must be a decl.
The following patch just doesn't diagnose attribute exclusions if the
other decl is erroneous (and thus we've already reported errors for it).

* attribs.c (decl_attribute): Don't diagnose attribute exclusions
if last_decl is error_mark_node or has such a TREE_TYPE.
* gcc.dg/pr94705.c: New test.
