ASoC: SOF: ipc4-control: Fix TOCTOU in sof_ipc4_bytes_put

In the Linux kernel, the following vulnerability has been resolved:

ASoC: SOF: ipc4-control: Fix TOCTOU in sof_ipc4_bytes_put

In sof_ipc4_bytes_put(), the copy size is derived from the old
data->size in the buffer rather than the incoming new data's size
field from ucontrol. If the new data has a different size, the copy
uses the wrong length: it may truncate valid data or copy stale bytes.

Fix by validating and using the incoming data's sof_abi_hdr.size from
ucontrol before copying.
