Better firmware module support for devices not connected to the internet (#854)

Devices not connected to the internet will either error when querying
firmware queries (e.g. P300) or return misleading information (e.g.
P100). This PR adds the cloud connect query to the initial queries and
bypasses the firmware module if not connected.
