Subject: blobmsg_json: fix int16 serialization
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

int16 blobmsg type is currently being serialized as uint16_t due to
missing cast during JSON output.

Following blobmsg content:

 bar-min: -32768 (i16)
 bar-max: 32767 (i16)

Produces following JSON:

 { "bar-min":32768,"bar-max":32767 }

Whereas one would expect:

 { "bar-min":-32768,"bar-max":32767 }
