remoteproc: virtio: Fix wdg cannot recovery remote processor
[ Upstream commit b327c72753d6a78de37aed6c35756f2ef62897ee ]
Recovery remote processor failed when wdg irq received:
[ 0.842574] remoteproc remoteproc0: crash detected in cix-dsp-rproc: type watchdog
[ 0.842750] remoteproc remoteproc0: handling crash #1 in cix-dsp-rproc
[ 0.842824] remoteproc remoteproc0: recovering cix-dsp-rproc
[ 0.843342] remoteproc remoteproc0: stopped remote processor cix-dsp-rproc
[ 0.847901] rproc-virtio rproc-virtio.0.auto: Failed to associate buffer
[ 0.847979] remoteproc remoteproc0: failed to probe subdevices for cix-dsp-rproc: -16
The reason is that dma coherent mem would not be released when
recovering the remote processor, due to rproc_virtio_remove()
would not be called, where the mem released. It will fail when
it try to allocate and associate buffer again.
Releasing reserved memory from rproc_virtio_dev_release(), instead of
rproc_virtio_remove().
