[PATCH -next] firmware: imx: scu: Fix possible memory leak in imx_scu_probe()

[Wei Yongjun]

'chan_name' is malloced in imx_scu_probe() and should be freed
before leaving from the error handling cases, otherwise it will
cause memory leak.

Fixes: edbee095fafb ("firmware: imx: add SCU firmware driver support")
