[PATCH] ASoC: SOF: ipc: Fix memory leak in sof_set_get_large_ctrl_data

[Navid Emamdoost]

In the implementation of sof_set_get_large_ctrl_data() there is a memory
leak in case an error. Release partdata if sof_get_ctrl_copy_params()
fails.

Fixes: 54d198d5019d ("ASoC: SOF: Propagate sof_get_ctrl_copy_params() error properly")
