"das16" sets a timer running in `das16_cmd_exec()` and sets
`devpriv->timer_running` to indicate that it is running. The timer
expiration routine `das16_timer_interrupt()` checks
`devpriv->timer_running` to check whether it needs to reschedule the
timer, but this is not synchronized with `das16_cmd_exec()`. Since
`das16_cancel()` acquires the `dev->spinlock` spin-lock when clearing
`devpriv->timer_running` and removing the timer from the queue, use the
same spin-lock in `das16_cmd_exec()` and `das16_timer_interrupt()`
around the setting and checking of `devpriv->timer_running`.
Since `das16_interrupt()` (called from `das16_timer_interrupt()`) checks
whether DMA is enabled in the device while holding `dev->spinlock`, and
DMA is enabled by `das16_cmd_exec()` around the time it schedules the
timer, enable the DMA in the device while holding the spin-lock.

The "das16" driver optionally uses a kernel timer and a DMA channel to
support asynchronous data acquisition, but currently never calls
`del_timer_sync()`. There is some possibility the timer routine could
still be scheduled to run when the comedi "detach" handler is run to
clean up the device and cause a certain amount of havoc. Avoid that by
calling `del_time_sync()` in the comedi "detach" handler
`das16_detach()` if the timer was initialized by the "attach" handler
`das16_attach()`. Use the timer's `data` member to tell whether it was
initialized or not.
