Subject: [PATCH v2 21/30] misc: mic: scif: scif_nodeqp: Fix a bunch of kerneldoc issues

Includes; missing function argument documentation, misnamed argument
tags, the promotion of obvious kerneldoc header candidates and an
ordering issue (functions must follow the kerneldoc which describes
them).

Fixes the following W=1 kernel build issues:

 drivers/misc/mic/scif/scif_nodeqp.c:730: warning: Function parameter or member 'unused' not described in 'scif_exit'
