sysfs: remove error messages for -EEXIST case
It is possible that the entry in sysfs already exists, one case of this is when a network device is renamed to bonding_masters. Anyway, in this case the proper error path is for device_rename to return an error code, not to generate bogus backtrace and errors. Also, to avoid possible races, the create link should be done before the remove link. This makes a device rename atomic operation like other renames.
