[ Upstream commit 4f32fb921b153ae9ea280e02a3e91509fffc03d3 ]

rdmavt uses a crazy system that looses the type checking when assinging
functions to struct ib_device function pointers. Because of this the
signature to this function was not changed when the below commit revised
things.

Fix the signature so we are not calling a function pointer with a
mismatched signature.

Fixes: 477864c8fcd9 ("IB/core: Let create_ah return extended response to user")
