Fix build error with RECORD_SIZE defined

[embhorn]

Description

MAX_RECORD_SIZE is defined in an enum, which would have a value of 0 during preprocessing. So if RECORD_SIZE is user defined, then the check RECORD_SIZE > MAX_RECORD_SIZE produces errors:

In file included from wolfcrypt/src/asn.c:200:

Should this go near #ifdef RECORD_SIZE at line 2276? Making this a macro is fine with me. I don't see any downstream issues.
