drm/amdgpu: clean up the amdgpu_cs_parser_bos 



In low memory conditions, kmalloc can fail. In such conditions
unlock the mutex for a clean exit.

We do not need to amdgpu_bo_list_put as it's been handled in the
amdgpu_cs_parser_fini.

Fixes: 737da536 ("drm/amdgpu: update the functions to use amdgpu version of hmm")
