IOT-2539 Targeted ignore of type-limits warning

This will turn of the type-limits warning in very
targeted area in the code. The code is checking
that the user passed in value is within limits.

Although it is very unlikely to be outsite the
expected values it is possible. Tthis selectivly
shuts off the warning for the two functions the
warning is found in.
