[ Upstream commit cee6c269b016ba89c62e34d6bccb103ee2c7de4f ]
If the state change to NVME_CTRL_CONNECTING fails, the dmesg is going to be like:
[ 293.689160] nvme nvme0: failed to mark controller CONNECTING [ 293.689160] nvme nvme0: Removing after probe failure status: 0
Even it prints the first line to indicate the situation, the second line is not proper because the status is 0 which means normally success of the previous operation.
This patch makes it indicate the proper error value when it fails. [ 25.932367] nvme nvme0: failed to mark controller CONNECTING [ 25.932369] nvme nvme0: Removing after probe failure status: -16
This situation is able to be easily reproduced by: root@target:~# rmmod nvme && modprobe nvme && rmmod nvme
