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:

-be{bits}_to_cpu(cpu_to_be{bits}(val))
+val
(and __be_to_cpu and ntoh varients)
Touched up with clang-format after.
