Having ringbuf->ring point to an engine is confusing, so rename it once

Doesn't do what it says in the commit message (which sounded like a good idea). This patch actually just renames the function intel_init_ring_buffer() to intel_init_engine(). However /most/ of the code in that function is to do with initialising a ringbuffer!
