ASoC: SOF: topology: Fix bytes control size checks 
When using the example SOF amp widget topology, KASAN dumps this
when the AMP bytes kcontrol gets loaded:

[ 9.579548] BUG: KASAN: slab-out-of-bounds in
sof_control_load+0x8cc/0xac0 [snd_sof]
[ 9.588194] Write of size 40 at addr ffff8882314559dc by task
systemd-udevd/2411

Fix that by rejecting the topology if the bytes data size > max_size

Fixes: 311ce4fe76 ("ASoC: SOF: Add support for loading topologies")
