>Description:
	gmirror list after gmirror deactivate command
>How-To-Repeat:
	 gmirror deactivate gm0 ad1; gmirror list
>Fix:

After  gmirror deactivate gm0 ad1 command
ad1 consumer disappers from the configration. This is very misleading.

# gmirror status
      Name    Status  Components
      mirror/gm0  COMPLETE  ad0
                            ad1

# gmirror deactivate gm0 ad1

# gmirror status
      Name    Status  Components
      mirror/gm0  DEGRADED  ad0

gmirror list reports State: DEGRADED and ad1 is also gone.

# gmirror list
Geom name: gm0
State: DEGRADED
Components: 2
Balance: round-robin
Slice: 4096
Flags: NONE
GenID: 0
SyncID: 2

Providers:
1. Name: mirror/gm0
   Mediasize: 160041885184 (149G)

Consumers:
1. Name: ad0
   Mediasize: 160041885696 (149G)
   Sectorsize: 512
   Mode: r1w1e1
   State: ACTIVE
   Priority: 1
   Flags: NONE
   GenID: 0
   SyncID: 2
   ID: 227080134
In my opinion, gmirror list should ad1 consumer as deactivated.

pjd at freebsd.org will take care of this pr.
Thanks,
