[PATCH v3 25/36] IB/rdmavt: Add the start of capability flags

[Dennis Dalessandro <dennis.dalessandro-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>]

Drivers will need a set of flags to dictate behavior to rdmavt. This patch
adds a placeholder and a spot for it to live, as well as a few flags
that will be used.
