powerpc/pseries/hibernation: remove redundant cacheinfo update 

[ Upstream commit b866459489 ]

Partitions with cache nodes in the device tree can encounter the
following warning on resume:

CPU 0 already accounted in PowerPC,POWER9@0(Data)
WARNING: CPU: 0 PID: 3177 at arch/powerpc/kernel/cacheinfo.c:197 cacheinfo_cpu_online+0x640/0x820

These calls to cacheinfo_cpu_offline/online have been redundant since
commit e610a466d1 ("powerpc/pseries/mobility: rebuild cacheinfo
hierarchy post-migration").

Fixes: e610a466d1 ("powerpc/pseries/mobility: rebuild cacheinfo hierarchy post-migration")
