audio: effect: prevents spurious call to remove/add device effects
Bug: 268441977
Test: make
When multiple clients are using a same input, each time a client is
added/removed, the audio path will be recreated, thus leading to
removing/adding the device effect on audio hal if a device effect is
used.
This CL prevents from removing/adding a device effect when a patch handle
is reused, by checking if it involves same sink device/source mix or sink mix
/source device.
