Subject: IB/{core, umad, cm}: Rename ib_init_ah_from_wc to
 ib_init_ah_attr_from_wc
Patch-mainline: v4.16-rc1
Git-commit: f6bdb14267ba799296a49a3de9c2811636b768f9
References: bsc#1103992 FATE#326009

Currently ib_init_ah_from_wc initializes address handle attributes and
not the address handle object itself.
To avoid confusion between ah_attr vs ah, ib_init_ah_from_wc is
renamed to ib_init_ah_attr_from_wc to reflect that its initialzes
ah_attr.
