[Mesa-dev] [PATCH] mesa/bufferobj: use mapping range in BufferSubData.

[Dave Airlie]

From: Dave Airlie <airlied at redhat.com>

According to GL4.5 spec:
An INVALID_OPERATION error is generated if any part of the speci-
fied buffer range is mapped with MapBufferRange or MapBuffer (see sec-
tion 6.3), unless it was mapped with MAP_PERSISTENT_BIT set in the Map-
BufferRange access flags.

So we should use the if range is mapped path.

This fixes:
GL45-CTS.buffer_storage.map_persistent_buffer_sub_data
