This reverts commit 0a732983f0.
Paul Nieminen and Dave Airlie pointed out on IRC that this shouldn't be
necessary. I was seeing visual corruption in X before I made this change, but
I can't reproduce that anymore so it was probably an unrelated issue.
airlied: modified the interface to drop busy return value, just return
it normally, also fixed int->uint32_t for domain

Using this call in OUT_BATCH_TABLE reduces radeonEmitState cpu usage from
9% to 5% and emit_vpu goes from 7% to 1.5%. I did use calgrind to profile
gears for cpu hotspots with r500 card.

BO are referenced once by reloc to make sure that they not destroyed
before we get a chance to flush the cmd stream, so we need to unreference
them once in cs submit or cs erase if cs i never submitted so bo can
be destructed.
Relocation now consist of the following informations (in this order) :
handle buffer object handle identifier
start_offset start offset of first data of the buffer object used by the cs
end_offset end offset of last data of the buffer object used by the cs
read_domain read domain (either VRAM, or GTT as GPU is invalid for CS)
write_domain write domain (either VRAM, or GTT as GPU is invalid for CS)
flags flags used for further optimization (like discard previous
buffer content or forget buffer content after cs which can
help in avoiding moving content in or out)
