ringbuf: Fix ordering of StaticRingbuffer_t

Browse Source 
When building on linux/host compilers (e.g., GCC), the compiler may add padding
depending on the size and order of the member types.

This commit fixes the ordering or the StaticRingbuffer_t such that it matches
the internal Ringbuffer_t. The "_Static_assert" is always enabled for all
compilers.
