[PATCH] ocxl: Simplify free_spa()

[Greg Kurz]

The only users of free_spa() are alloc_link() and free_link(), and
in both cases:

- link->spa != NULL

- free_spa(link) is immediatly followed by kfree(link)

The check isn't needed, and it doesn't bring much to clear the link->spa
pointer. Drop both.
