Reuse of error (sub)codes

[ted-miller]

There are multiple instances of the SUBCODE_FAIL_MP_NICDATA error code in different source files. Although they both essentially have the same meaning, it is impossible to know exactly which line of code raised the error. This makes troubleshooting more difficult.

We should go through and make sure that no error code is repeated anywhere in the code.

SUBCODE_FAIL_MP_NICDATA instances:

motoros2/src/CommunicationExecutor.c

Line 67 in 9f1c599

SUBCODE_FAIL_MP_NICDATA,

and

motoros2/src/ConfigFile.c

Line 134 in 9f1c599

SUBCODE_FAIL_MP_NICDATA,

I've got something for this in main...gavanderhoorn:motoros2:platform_lib_update_v210.
