Replace the raw atomic_t reference counting of zone write plugs with a

I don't quite see the point, but if Jens wants to take it the code
changes look correct to me:
The point is only to avoid kernel bots screaming about the use of atomic for
refcounting. Nothing more than that.
There may be better approaches to achieve this goal, e.g. introducing an
annotation scheme that makes these bots ignore zwplug->ref. I prefer the
annotation approach because I'm concerned that this patch will have a
negative performance for ZNS and ZUFS devices.
Thanks,
