qcacmn: Deinit CE tasklet work before CE Cleanup

During freeing up of hif_config_de resources, the ce tasklet workers
are deinitialized after the ce cleanup is done. This causes a race
condition between shutdown and ce tasklet in case rescheduling of ce
taslket is done.

Deinitialize the taslket workers before ce structures are deinitialized.
