ASoC: SOF: validate probe info element counts
Probe information replies contain a firmware-provided element count. IPC3
uses that count to copy an array, then returns the unchecked count to its
caller. A short reply can therefore make the caller walk beyond the copied
array.
IPC4 similarly uses the count both to allocate the destination array and
to walk the reply. On 32-bit systems the allocation size can wrap, while on
all systems an excessive count reads beyond the reply payload.
Validate each count against the actual reply size before copying or
allocating the array, and use kcalloc() for the IPC4 allocation.
