Handle errors from functions that now return int

Browse source 
A few functions were changed from returning void to returning int three
commits ago. Make sure their callers check the return values.

This commits was basically a matter of declaring newly-int-returning
functions MBEDTLS_CHECK_RETURN_CRITICAL and then fixing the resulting
warnings. A few functions had to be made int in the process; they were
applied the same process as well.
