ASoC: max98390: Fix potential crash during param fw loading
malformed firmware file can cause out-of-bound access and crash
during dsm_param bin loading.
- add MIN/MAX param size to avoid out-of-bound access.
- read start addr and size of param and check bound.
- add condition that fw->size > param_size + _PAYLOAD_OFFSET
to confirm enough data.
