[PATCH] PM / devfreq: Fix faulty error message

[Deva Ramasubramanian <dramasub@codeaurora.org>]

The misleading log "releasing devfreq which doesn't exist" prints out
for well behaved clients.  This is due to the fact that _remove_devfreq
calls itself recursively by proxy (via put_device()).  The second time
_devfreq_remove is called the respective device has already been
deleted, causing the misleading warning.

So just skip printing the message if _devfreq_remove was called via
put_device().
