[PATCH 4/7] mpi3mr: misc changes and use __builtin_return_address for debug

[Kashyap Desai <kashyap.desai@broadcom.com>]

[-- Attachment #1: Type: text/plain, Size: 5813 bytes --]

No Functional changes.

Some minor variable name changes.
Use __builtin_return_address in some of the functions which are called
from multiple callers. Doing this we can avoid multiple debug prints.
