RDMA/cm: Use IBA functions for simple get/set acessors

RDMA/cm: Use IBA functions for simple get/set acessors

Use a Coccinelle spatch to replace CM helper functions with IBA_GET/SET
versions. Applied with

$ spatch --sp-file edits.sp --in-place drivers/infiniband/core/cm.c

The spatch file was generated using the template pattern:

@@
expression val;
{struct} *msg;
@@
- {old_setter}
+ IBA_SET({new_name}, msg, val)
@@
{struct} *msg;
@@
- {old_getter}
+ IBA_GET({new_name}, msg)

Iterated for every IBA_CHECK_GET()/IBA_CHECK_GET() pairing. Touched up
with clang-format after.
