c: Avoid clobbering TREE_TYPE (error_mark_node) [PR0]

The following testcase ICEs during error recovery, because finish_decl
overwrites TREE_TYPE (error_mark_node), which better should stay always
to be error_mark_node.

PR c/0
* c-decl.c (finish_decl): Don't overwrite TREE_TYPE of
error_mark_node.

* gcc.dg/pr0.c: New test.
