[PATCH V2 02/12] nvmet: for pt I/O commands use likely for ns check

[Chaitanya Kulkarni]

I/O commands (nvme_cmd_read, nvme_cmd_write) are most common commands
when accessing passthru controller. Since for I/O commands ns is always
present and the condition is marked as likely. Annotate post request
submission ns check with likely which is dependent on earlier the ns
check likely condition.
