[PATCH] ring-buffer: drop unneeded semicolon

When a function-like macro expands to an expression, that expression
doesn't need a semicolon after it. All uses have been verified to
have their own semicolons.
This was found using the following Coccinelle semantic patch:
@r@
identifier i : script:ocaml() { String.lowercase_ascii i = i };
expression e;
@@
*#define i(...) e;
