[ Upstream commit e804d5abe2d74cfe23f5f83be580d1cdc9307111 ]
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.
