Cannot open device key protected by pass phrase

[tjamison]

Attempting to connect a client (whose device key has a pass phrase) to a backend (whose device key has no pass phrase) results in a crash on the client side.

Client side console output:

(rvi@tjamison-Precision-T5610)1> 2016-07-06 16:05:02.517 [error] <0.194.0>@dlink_tls_conn:handle_upgrade:407 Cannot upgrade to TLS: {error,{options,{keyfile,"/usr/lib/rvi_core/priv/keys/device_key.pem",{error,enoent}}}}

Backend side console output:

Removing the pass phrase from the client's key results in successful connection.
