nvme: delete all namespaces in _remove_nvmet_subsystem()

A subsystem might have more than one namespace, so delete all of them in
_remove_nvmet_subsystem().

This change was to be made before the commit 67e25d7 ("nvme/052: do
not create namespace when setting up the target"), which assumes that
_remove_nvmet_subsystem() delets all namespaces. However, commit order
was modified then the test case nvme/052 now fails without this commit.
