[PATCH 1/5] nvme-core: Make nvme_init/uninit_ctrl setup/teardown symmetric

[Sagi Grimberg]

>>> From: Roy Shterman <roys at lightbitslabs.com>
>>>
>>> Its strange to have some of the cleanup for nvme_init_ctrl in
>>> nvme_free_ctrl. This cause us to have some magic ctrl refcount
>>> handling in controller initialization error paths.
>>>
>>> Make the init/uninit symmetric so we can have a sane and
>>> maintainable error sequences.
>>
>> This totally conflicts with my refcount / device rework in the
>> mpath patchset..
> 
> I know...
> 
> Do you want me to rebase on top of your next round of patches?
