[PATCH v2 4/4] media: imx8-isi: clean up already-initialized pipes on probe failure

[Xiaolei Wang]

When mxc_isi_pipe_init() fails partway through the channel loop or
when mxc_isi_v4l2_init() fails, the already initialized pipes are
not cleaned up.

Fix this by calling mxc_isi_pipe_cleanup() for each already-initialized
pipe in the err_xbar error path.
