locking/refcount: Consolidate implementations of refcount_t
[ Upstream commit fb041bb7c0a918b95c6889fc965cdc4a75b4c0ca ]
The generic implementation of refcount_t should be good enough for
everybody, so remove ARCH_HAS_REFCOUNT and REFCOUNT_FULL entirely,
leaving the generic implementation enabled unconditionally.
