drm/i915/perf: Remove gtt_offset from stream->oa_buffer.head/.tail
There is no reason to add gtt_offset to the cached head/tail pointers
stream->oa_buffer.head and stream->oa_buffer.tail. This causes the code to
constantly add gtt_offset and subtract gtt_offset and is error
prone.
It is much simpler to maintain stream->oa_buffer.head and
stream->oa_buffer.tail without adding gtt_offset to them and just allow for
the gtt_offset when reading/writing from/to HW registers.
v2: Minor tweak to commit message due to dropping patch in previous series
