nvme: split nvme_update_zone_info
nvme_update_zone_info does (admin queue) I/O to the device and can fail.
We fail to abort the queue limits update if that happen, but really
should avoid with the frozen I/O queue as much as possible anyway.
Split the logic into a helper to query the information that can be
called on an unfrozen queue and one to apply it to the queue limits.
Fixes: 9b130d681443 ("nvme: use the atomic queue limits update API")
