Move length check into mbedtls_x509_memcasecmp()

Browse source 
At every occasion where we're using `mbedtls_x509_memcasecmp()` we're
checking that the two buffer lengths coincide before making the call.

This commit saves a few bytes of code by moving this length check
to `mbedtls_x509_memcasecmp()`.
