According to the NVMe specification, the response dword 0 value of the
Connect command is based on status code: return cntlid for successful
compeltion return IPO and IATTR for connect invalid parameters. Fix
a missing error information for a zero sized queue, and return the
cntlid also for I/O queue Connect commands.
