misc: mic: scif: scif_fence: Fix a bunch of different documentation issues

Firstly add missing descriptions for every use of 'scifdev', then
correct incorrect formatting of existing function argument descriptions
changing to the expected format of '@.*: ', finally add missing
description for function argument 'mark'.

Fixes the following W=1 warnings:

 drivers/misc/mic/scif/scif_fence.c:19: warning: Function parameter or member 'scifdev' not described in 'scif_recv_mark'
