drm/radeon: make fence wait in suballocator uninterrruptable

Commit 254986e ("drm/radeon: Use the drm suballocation manager implementation.")
made the fence wait in amdgpu_sa_bo_new() interruptible but there is no
code to handle an interrupt. This caused the kernel to randomly explode
in high-VRAM-pressure situations so make it uninterruptible again.
