drm/amd: Make fence wait in suballocator uninterruptible

Commit c103a23
("drm/amd: Convert amdgpu to use suballocation helper.")
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.
