Revert "radeon: Reinstate sync in radeon_crtc_show/hide_cursor."
This reverts commit 0241cac643fa1c08a45ea44f5c670b290e760ad8.
Taking the DRI lock in paths called from the SIGIO handler isn't safe. For
example, the SIGIO handler may be called while the lock is held by an AIGLX
context, resulting in deadlock. See e.g.
https://bugs.freedesktop.org/show_bug.cgi?id=13005 .
