locking: Simplify spinlock inlining

For !DEBUG_SPINLOCK && !PREEMPT && SMP the spin_unlock()
functions were always inlined by using special defines which
would call the __raw* functions.

The out-of-line variants for these functions would be generated
anyway.

Use the new per unlock/locking variant mechanism to force
inlining of the unlock functions like before. This is not a
functional change, we just get rid of one additional way to
force inlining.
