i965: Delete more misleading comments.

brw_bo_wait_rendering used to take a brw_context pointer for perf_debug
messages about stalls.  Chris eliminated that in 833108ac14ade91f54cc6e.
This message about passing NULL to avoid those warnings is no longer
relevant, and just adds confusion.  So, drop it.
