radeon/winsys: correct RADEON_GEM_WAIT_IDLE use
RADEON_GEM_WAIT_IDLE is declared DRM_IOW but mesa
uses it with drmCommandWriteRead instead of drmCommandWrite
which leads to the ioctl being unmatched and returning an
error on at least OpenBSD.
Problem originally noticed in libdrm by Mark Kettenis.
Dave Airlie pointed out that mesa has the same issue.
