Subject: nvme: send Identify with CNS 06h only to I/O controllers
Patch-mainline: v6.3-rc4
Git-commit: def84ab600b71ea3fcc422a876d5d0d0daa7d4f3
References: bsc#1209693
Identify CNS 06h (I/O Command Set Specific Identify Controller data
structure) is supported only on i/o controllers.
But nvme_init_non_mdts_limits() currently invokes this on all
controllers. Correct this by ensuring this is sent to I/O
controllers only.
