[PATCH V2 6/7] drm/amdgpu: Ensure kunmap is called on error

[ira.weiny@intel.com]

From: Ira Weiny <ira.weiny@intel.com>

The default case leaves the buffer object mapped in error.

Add amdgpu_bo_kunmap() to that case to ensure the mapping is cleaned up.

NOTE: It seems like this function could use a fair bit of refactoring
but this is the easiest way to fix the actual bug.
