We already grab 2 device-global locks (write-sema rdev->pm.mclk_lock and rdev->ring_lock), adding another global mutex won't serialize this code more. And since there's really nothing interesting that gets protected in radeon by dev->struct mutex (we only have the global z buffer owners and it's still serializing gem bo destruction in the drm core - which is irrelevant since radeon uses ttm anyway internally) this doesn't add protection. Remove it.
