[PATCH v2] hw/nvme/ctrl: fix csi field for cns 0x00 and 0x11

[Gollu Appalanaidu]

As per the TP 4056d Namespace types CNS 0x00 and CNS 0x11
CSI field shouldn't use but it is being used for these two
Identify command CNS values, fix that.

Remove 'nvme_csi_has_nvm_support()' helper as suggested by
Klaus we can safely assume NVM command set support for all
namespaces.
