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

Use a Coccinelle spatch script to replace CM helper functions that
return/accept BE values 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}(msg, val)
+ IBA_SET({new_name}, msg, be{bits}_to_cpu(val))
@@
{struct} *msg;
@@
- {old_getter}(msg)
+ cpu_to_be{bits}(IBA_GET({new_name}, msg))

Iterated for every IBA_CHECK_GET_BE()/IBA_CHECK_SET_BE() pairing.

And the below iterated over all byte sizes to remove doubled byte swaps:

@@
expression val;
@@
-be{bits}_to_cpu(cpu_to_be{bits}(val))
+val

(and __be_to_cpu and ntoh varients)

Touched up with clang-format after.
