ASoC: topology: Check size mismatch of ABI objects before parsing

Browse source

If size mismatch of manifest, ABI headers or elements is found, stop
parsing topology info and return the error.

New fields may be append to the tail of ABI objects which will cause
object size to increase. If user space and kernel use different versions
of ABI, size mismatch will be detected here.
