MIPS: smp-cps: Convert smp_mb__after_atomic_dec()

Commit 91bbefe6b0fc "arch,mips: Convert smp_mb__*()" replaced the
smp_mb__after_atomic_dec function with smp_mb__after_atomic, whilst
commit 1d8f1f5a780a "MIPS: smp-cps: hotplug support" introduced a new
use of it. Replace that use with smp_mb__after_atomic in order to avoid
a build failure:

  arch/mips/kernel/smp-cps.c: In function 'cps_cpu_disable':
  arch/mips/kernel/smp-cps.c:304:2: error: 'smp_mb__after_atomic_dec' is
    deprecated (declared at include/linux/atomic.h:35)
    [-Werror=deprecated-declarations]
