ring-buffer: Add missing unlock
In some error handling cases the lock is not unlocked. The return is
converted to a goto, to share the unlock at the end of the function.
A simplified version of the semantic patch that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@r exists@
expression E1;
identifier f;
@@
f (...) { <+...
* spin_lock_irq (E1,...);
... when != E1
* return ...;
...+> }
// </smpl>
