Bugfix
   * Fix a memory leak in mbedtls_md_setup() when using HMAC under low memory
     conditions. Reported and fix suggested by Guido Vranken in #3486.
Fix memory leak in mbedtls_md_setup with HMAC mbedtls_md_setup() allocates a hash-specific context and then, if requested, an extra HMAC context. If the second allocation failed, the hash context was not freed. Fix this by ensuring that the mbedtls_md_context_t object is always in a consistent state, in particular, that the md_info field is always set. For robustness, ensure that the object is in a consistent state even on errors (other than BAD_INPUT_DATA if the object was not in a consistent state on entry).
