[PATCH 16/23] IB/hfi1: Use reference count wrapper for MRs

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

From: Sebastian Sanchez <sebastian.sanchez-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

Some parts of the code don't use the standard driver
wrapper for memory region reference counters. Use the
standard driver wrapper throughout the code.
