Subject: RDMA/rdmavt: Fix rvt_create_ah function signature
Patch-mainline: v4.20-rc5
Git-commit: 4f32fb921b153ae9ea280e02a3e91509fffc03d3
References: bsc#1103992 FATE#326009
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")
