checkpatch: only warn for empty lines before closing braces by themselves

This check was intended to catch extra newlines at the end of a function
definition, but it would trigger on any closing brace, including those
of inline functions and macro definitions, triggering false positives.
Now, only closing braces on a line by themselves trigger this check.

Tested with:

$ cat test.h
/* test.h - Test file */

static inline int foo(void) { return 0; }

static inline int bar(void)
{
        return 1;

}

$ ./scripts/checkpatch.pl --strict -f test.h # Before this commit
CHECK: Blank lines aren't necessary before a close brace '}'
+
+static inline int foo(void) { return 0; }

CHECK: Blank lines aren't necessary before a close brace '}'
+
+}

total: 0 errors, 0 warnings, 2 checks, 9 lines checked

$ ./scripts/checkpatch.pl --strict -f test.h # After this commit
CHECK: Blank lines aren't necessary before a close brace '}'
+
+}

total: 0 errors, 0 warnings, 1 checks, 9 lines checked
