[PATCH] firmware: imx-dsp: Fix an error handling path in imx_dsp_setup_channels()

[Christophe JAILLET]

If mbox_request_channel_byname() fails, the memory allocated a few lines
above still need to be freed before going to the error handling path.

Fixes: 046326989a18 ("firmware: imx: Save channel name for further use")

The Fixes tag is not really accurate, the issue was already there before,
with other emory leaks.
However, I think that the Fixes tag above is much more logical.

Feel free to update!
