Tasklet get stuck when cds_is_driver_recovering and the driver
state is unloading. It happens due to race between schedule of
tasklet and tasklet_kill. Here one thread is trying to disable &
kill the tasklet while another thread is trying to concurrently
schedule it.
Cancel the tasklet work and make tasklets[i].inited = false before
disabling the tasklet in ce_tasklet_kill() and validate if tasket is
inited before rescheduling the tasklet.
