[PULL 12/38] hw/block/nvme: fix Close Zone

[Klaus Jensen]

From: Dmitry Fomichev <dmitry.fomichev@wdc.com>

Implicitly and Explicitly Open zones can be closed by Close Zone
management function. This got broken by a recent commit ("hw/block/nvme:
refactor zone resource management") and now such commands fail with
Invalid Zone State Transition status.

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