nvme-apple: Use acquire/release for queue enabled state

apple_nvme_init_queue() initializes queue state and then marks the queue
enabled. The interrupt and request paths check enabled before using that
queue state.

The old wmb() after WRITE_ONCE(enabled, true) does not publish the
earlier initialization before enabled becomes visible. Use a release store
when enabling the queue and acquire loads when testing it.

Although the shutdown-side enabled accesses are not used for publishing
queue initialization, use helpers for them as well for consistency.
