checkpatch: fix extraneous EXPORT_SYMBOL* warnings

checkpatch: fix extraneous EXPORT_SYMBOL* warnings

These are caused by checkpatch incorrectly parsing its internal
representation of a statement block for struct's (or anything else that is
a statement block encapsulated in {}'s that also ends with a ';').  Fix
this by properly parsing a statement block.

An example:

	+struct dummy_type dummy = {
	+	.foo	= "baz",
	+};
	+EXPORT_SYMBOL_GPL(dummy);
	+
	+static int dummy_func(void)
	+{
	+	return -EDUMMYCODE;
	+}
	+EXPORT_SYMBOL_GPL(dummy_func);

	WARNING: EXPORT_SYMBOL(foo); should immediately \
		follow its function/variable
	#19: FILE: dummy.c:4:
	+EXPORT_SYMBOL_GPL(dummy);

The above warning is issued when it should not be.
