powerpc/cell/oprofile: Avoid double vfree of profile buffer
If an error occurs on opcontrol start, the event and per cpu buffers are released. If later opcontrol shutdown is called then the free function will be called again to free buffers that no longer exist. This results in a kernel oops. The following changes prevent the call to delete buffers that don't exist.
