locking/atomic: scripts: remove leftover "${mult}" 



We removed cmpxchg_double() and variants in commit:

  b4cf83b2d1da40b2 ("arch: Remove cmpxchg_double")

Which removed the need for "${mult}" in the instrumentation logic.
Unfortunately we missed an instance of "${mult}".

There is no change to the generated header.
There should be no functional change as a result of this patch.
