[PATCH 2/5] IB/user_mad: Remove local start/end port variable and use the new common functions

[ira.weiny-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org]

From: Ira Weiny <ira.weiny-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

The start_port and end_port was duplicated data.

Use the new common rdma_[start|end]_port functions instead and remove the
unnecessary duplicated data.
