locking/refcounts: Do not force refcount_t usage as GPL-only export
commit b562c171cf011d297059bd0265742eb5fab0ad2f upstream.
The refcount_t protection on x86 was not intended to use the stricter
GPL export. This adjusts the linkage again to avoid a regression in
the availability of the refcount API.

Fixes: 7a46ec0e2f48 ("locking/refcounts, x86/asm: Implement fast refcount overflow protection")
