audio_state must be checked but we could move that into
pa_bluetooth_device_any_audio_connected(), where other similar
conditions are checked.

In this case the function could be removed entirely by directly
checking device_info_valid, as you suggest, which would make the code
more readable. Functions like pa_bluetooth_discovery_get_by_address()
would return the device no matter the state of the audio interface.
This make sense IMO and it would make no difference in the current
codebase since modules make use of devices only after the discovery
hook has been triggered.

Yes, that's why it was first in the patchset.
