bus: mhi: host: Use kzalloc_flex
Change kzalloc + kzalloc to just kzalloc with a flexible array member.
Add __counted_by for extra runtime analysis when requested.
Move counting assignment immediately after allocation as required by
__counted_by.
Move mhi_buf definition as a complete definition as needed for flex
arrays. It's not a pointer anymore.
