[PATCH][next] nvmet: remove redundant assignments of variable status

[Colin King]

From: Colin Ian King <colin.king@canonical.com>

There are two occurrances where variable status is being assigned a
value that is never read and it is being re-assigned a new value
almost immediately afterwards on an error exit path. The assignments
are redundant and can be removed.
