247c405098 drm/radeon: fix userptr lockup
We shouldn't try to reserve and wait for a BO that isn't bound. Otherwise
we can run into a deadlock if we have a fault during binding the BO.

49ecb10e01 drm/radeon: allow creating overlapping userptrs
Similar to the Intel implementation, but instead of just falling back to a
global linear list when we have an overlapping userptr request we accumulate
all overlapping userptrs in a local list.
