x86/alternative: Drop smp_locks glue
This was there to be able to patch out locking instructions when running
a SMP kernel build on a UP CPU. The times are long gone when single-CPU
x86 machines were relevant so drop that machinery and simplify the code
considerably.
LOCK_PREFIX needs to stay for when one wants to do a UP build for
whatever reason. That'll go away when CONFIG_SMP becomes unconditional.
Kill a bunch of leftover, unused prototypes while at it.
