staging/ks7010: replace SME taslet with work
Tasklets have long been deprecated as being too heavy on the system by running in irq context - and this is not a performance critical path. If a higher priority process wants to run, it must wait for the tasklet to finish before doing so. The execution of the SME event will now occur in task context. There are, however, changes in concurrency. Workqueues, unlike tasklets, are not serialized among themselves and can run concurrently updating sme_i.qhead. However, the current code is already exposed in same ways, regardless of the deferral mechanism, in that hostif_sme_enqueue() does unserialized enqueues updating sme_i.qtail. Also get rid of the bogus (power save) tasklet enabling, as it is never disabled to begin with.
