[PATCH v2 07/22] bluetooth: Fix check if transport exists before acquire

[mikel.astiz.oss@xxxxxxxxx (Mikel Astiz)]

From: Mikel Astiz <mikel.astiz@xxxxxxxxxxxx>

The transport might have disapeared exactly before acquiring, so we
should avoid an assertion failure, in this case inside the function
pa_bluetooth_discovery_get_by_path().
