[PATCH] nvme-cli: Fix to the logic of the nvme list-ns <device> -a command.

[Chaitanya Kulkarni]

This fix will reverse the logic of the -a parm in the nvme list-ns
command. Currently, the -a option only shows the attached namespaces
and not all the namespaces. By removing the extra ! it will show attached
inactive namespaces with -a option as mentioned in the help text.

Example : Controller has 3 namespaces, two of them are not attached.

Default exection with “!!” :-
$ nvme list-ns  /dev/nvme0 -a
[   0]:0x1

Execution with “!” :-
 nvme list-ns  /dev/nvme0 -a
[   0]:0x1
[   1]:0x2
[   2]:0x3
