[PATCH] hw/block/nvme: fix Close Zone

[Dmitry Fomichev]

Implicitly and Explicitly Open zones can be closed by Close Zone
management function. This got broken by a recent commit and now such
commands fail with Invalid Zone State Transition status.

Modify nvm_zrm_close() function to make Close Zone work correctly.
