devlink: split out core code Move core code into a separate file. It's spread around the main file which makes refactoring and figuring out how devlink works harder. Move the xarray, all the most core devlink instance code out like locking, ref counting, alloc, register, etc. Leave port stuff in leftover.c, if we want to move port code it'd probably be to its own file.

devlink: keep the instance mutex alive until references are gone The reference needs to keep the instance memory around, but also the instance lock must remain valid. Users will take the lock, check registration status and release the lock. mutex_destroy() etc. belong in the same place as the freeing of the memory. Unfortunately lockdep_unregister_key() sleeps so we need to switch the an rcu_work. Note that the problem is a bit hard to repro, because devlink_pernet_pre_exit() iterates over registered instances. AFAIU the instances must get devlink_free()d concurrently with the namespace getting deleted for the problem to occur.

If a xarray has two entries one which spans indexes 0-3 and one at index 4 xa_find_after(0) will return the entry at index 4. Having to juggle the two callbacks, however, is unnecessary in case of the devlink xarray, as there is 1:1 relationship with indexes. Always use xa_find() and increment the index manually.

devlink: always check if the devlink instance is registered Always check under the instance lock whether the devlink instance is still / already registered. This is a no-op for the most part, as the unregistration path currently waits for all references. On the init path, however, we may temporarily open up a race with netdev code, if netdevs are registered before the devlink instance. This is temporary, the next change fixes it, and this commit has been split out for the ease of review.
