42f921a cpufreq: remove sysfs files for CPUs which failed to come back after resume

Currently we are getting this on suspend/resume:

------------[ cut here ]------------ WARNING: CPU: 0 PID: 877 at fs/sysfs/dir.c:52 sysfs_warn_dup+0x68/0x84() sysfs: cannot create duplicate filename '/devices/system/cpu/cpu1/cpufreq'

...

Fix this by removing sysfs link for cpufreq directory when cpu removed isn't policy->cpu.
