[isci-rnc PATCH v1 27/37] isci: Add protocol indicator for TMF requests.

[Dan Williams <dan.j.williams@xxxxxxxxx>]

From: Jeff Skirvin <jeffrey.d.skirvin@xxxxxxxxx>

Requests contructed as task management requests need to have the protocol
indicator set so the completion decode can observe any RNC suspension
conditions.
