Subject: nvmet: fix Identify Controller handling
Patch-mainline: v6.4-rc1
Git-commit: 62904b3b333e7f3c0f879dc3513295eee5765c9f
References: git-fixes

The identify command with cns set to NVME_ID_CNS_CTRL does not depend on
the command set. The execution of this command should thus not look at
the csi specified in the command. Simplify nvmet_execute_identify() to
directly call nvmet_execute_identify_ctrl() without the csi switch-case.

Fixes: ab5d0b38c047 ("nvmet: add Command Set Identifier support")
