nvmet: fix Identify Controller handling
[ Upstream commit 62904b3b333e7f3c0f879dc3513295eee5765c9f ]
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.
