accel/amdxdna: Call dma_buf_vmap_unlocked() for imported object

Browse source

[ Upstream commit 457f4393d0 ]

In amdxdna_gem_obj_vmap(), calling dma_buf_vmap() triggers a kernel
warning if LOCKDEP is enabled. So for imported object, use
dma_buf_vmap_unlocked(). Then, use drm_gem_vmap() for other objects.
The similar change applies to vunmap code.
