freedreno: Stop forcing ALLOW_MAPPED_BUFFERS_DURING_EXEC off.

The default is to not throw GL errors when drawing with mapped
buffers, but we were forcing it on for unclear reasons.  Internally we
keep all our buffers mapped anyway, so it should be a no-op other than
reducing CPU overhead (.23% in a perf report for WebGL fishtank)
