RDMA/cm: Use IBA functions for complex structure members

Browse Source 
Use a Coccinelle spatch to replace CM structure members used as
structures, arrays, or pointers 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 src;
expression len;
{struct} *msg;
@@
- memcpy(msg->{old_name}, src, len)
+ IBA_SET_MEM({new_name}, msg, src, len)
@@
{struct} *msg;
identifier x;
@@
- msg->{old_name}.x
+ IBA_GET_MEM_PTR({new_name}, msg)->x
@@
{struct} *msg;
@@
- &msg->{old_name}
+ IBA_GET_MEM_PTR({new_name}, msg)

For GIDs:
@@
{struct} *msg;
@@
- msg->{old_name}
+ *IBA_GET_MEM_PTR({new_name}, msg)

For non-GIDs:
@@
{struct} *msg;
@@
- msg->{old_name}
+ IBA_GET_MEM_PTR({new_name}, msg)

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