ISP channels are not released cleanly if the IVC send for CAPTURE_CHANNEL_ISP_RELEASE_REQ were to fail, leaving the rest of the release steps undone, including unregistering the capture and control callbacks. This will prevent any new channel setups, e.g., after an app restart, because the channel is deemed busy. Another problem with ISP channel release is that were the aforementioned IVC sends to fail, the driver will not attempt an RCE reboot to recover the IVC communications. Similarly, if the channel reset IVC request fails or returns an error, the pending capture and program buffers won't be unpinned and their related waits won't be completed. This fix always performs the cleanups regardless of the fate of the control channel requests.
