Subject: [PATCH] soundwire: bus: Fix device found flag correctly

found flag that is used to indicate SoundWire device on the bus is
not reset correctly after one iteration, this could miss adding devices
that are enumerated on the bus but on in device list.

Fixes: d52d7a1be02c ("soundwire: Add Slave status handling helpers")
