mosquitto_reinitialise documentation error

[rroguski]

Hi,

had a nasty bug in my code and by accident found a documentation error in
https://github.com/eclipse/mosquitto/blob/master/include/mosquitto.h#L327

In the function's implementation https://github.com/eclipse/mosquitto/blob/master/lib/mosquitto.c#L140 one can see that instead of returning MOSQ_ERR_NOMEM it returns MOSQ_ERR_MALFORMED_UTF8 here: https://github.com/eclipse/mosquitto/blob/master/lib/mosquitto.c#L167

Thank you! It actually should be returning MOSQ_ERR_NOMEM as well as MOSQ_ERR_MALFORMED_UTF8. I've fixed both parts.
