Krzysztof Chruscinski 58942f3f13 lib: os: ring_buffer: Fix race condition 
Ring buffer claims that no synchronization is needed
when there is a single producer and single consumer.
However, recent changes have broken that promise since
indexes rewind mechanism was modifing head and tail
when consuming. Patch fixes that by spliting rewinding
of indexes so that producer rewinds tail only and
consumer rewinds head.
