Rob Norris 2ca6e880da spl: remove old atomic lock
Long ago, SPL atomics were implemented as a global spinlock over
conventional operations. In 5e9b5d832b (2009-10) they was converted to
proper atomics, with the spinlock retained as a fallback.

The switch to compile with the fallback was later removed in a91258913f
(2018-05), but the code it enabled wasn't. So lets do that.
