[PATCH 05/14] nvmet: remove repeated call for changed-ns log page

[Chaitanya Kulkarni]

Return status from nvmet_execute_get_log_page_changed_ns() and complete
the request in nvmet_execute_get_log_page(). This reduces number of
repeated nvmet_req_complete() calls for log page handlers.

Also, now we can get rid of the goto and out label needed for request
completion and directly return.
